I didn't see a thread for Jaco tires, and thought there should be one. I just switched back to Jaco's after running another brand for about a year. Last time out I was WAY loose at about the 2 min mark on. I was told that the "New" componds Jaco is putting out is the same as the other brand. So I went with the same setup.

LF - White (25 duro?)
RF - Black
LR - White
RR - Yellow (30 duro?) also tried a white RR with same result.

This is actually less aggresive than the other brand, as I was running a grey RF.

I was running at Rosewood, in 13.5. Track had low grip 160'.

I think the common Jaco setup for flat carpet stock is:

White LR
Gray RR
Gray LF
Black RF

That's what I run.

I have had the same issue running 3 whites and a black in 13.5. The car would free up so much throughout a run. The only way I could make it 4 minutes was to have the car very tight for the first 45 sec to a minute and then by the last minute the car was pretty neutral. If the car started out neutral I was pulling off because it was too loose the last minute. This past week I was having this issue and I replaced the lr with a TM white and the car got some better and then once I replaced both jaco rears with TM's the car was the same from the first lap until the end. It seems like the traction compound doesn't last on the Jaco whites. I was using Jack the Gripper.

Yeah, I am using Jack as well. I think I am going to try...

LF - Soft Pink
RF - Lilac
LR - Soft Pink
RR - Pink

That is what a "team" driver is running in 13.5. I have never liked pinks and purples (BSR anyway) so I wanted to try the whites.

I would recommend the last setup for tires on a low grip track ..... The tires will give you the grip you need for the entire race ....

we run 3 Soft pinks and a purple RF in all classes above 17.5 ie 13.5 and 10.5 and mod ......

Low grip means you need maximum grip ...... High grip will work with the 2 greys and a whire LR and a blck RF

One other thing to consider is the offset of the Jaco wheels is a little different than the BSR's. They make the front a little narrower, so you may need to shim them out on the axles to make them the same overall dimensions you had before. The rears are also different, which means you may need to shim the rears out as well.

Hi kevin Back in Wisconsin Miss you racing !!!!!


ROCKET

Hey Rocket, I had to get further away from you East Coast guys, you're too fast for me!!! LOL Don't worry, I'm preparing for a comeback already, won't be long and I might see ya round.

So when would you guys run whites or yellows? Also can I assume that yellow is what the old white was 30 duro? With the new white being 25?

The only thing I ran in 13.5 on carpet at the end of our carpet season was JACO 3 soft pinks and a LILAC RF.

J-Dub, another good set-up for 17.5 is RF black, LF green, LR green and RR white or sometime grey if you need less traction!! on low bite track i prefer this set-up over the purple/pink for 17.5 class....

Pace

What about outdoor racing.....Purples, double pinks, pinks, what else?
Rocket when u coming and play with us @ t&l?

Has anybody ran the new Jaco Foam tires for the Traxxas Line of cars? Iam really wanting to run them this fall/winter. Do they fit on the older XL-5 trucks? Or is it only the VXL models???

JACO tire TQed, Win and set track record in 2 class at Barre Vt for the Turkey Shootout...these fast tire put my car in the winner Circle again in 2 class, 17.5 1s semi pro and 13.5 1s pro....Big thanks to Jack for the support over the years and for the best tire in buisness.....the results at any big race show the performance of these tire!!:thumbsup:

Pace

Team JACO tire

PAce Congrats on the wins with JACO ... Jacks tires are great year in and year out ....Trying to get to the track to test for Snowbirds just busy w work ...SRM

J-Dub, I'd try the White Rears (Or even Yellow Rears in Some Cases), Black RF, and try a Green LF......

It seems like from what you are saying (And I've seen it Happen) the Yellow front is gumming up Half way through the run, and making the car hook.....The Green won't gum up as bad, if not at all.....It will also wear more evenly ( Not Completely, But Closer) with the RF.... Worth a Shot.....:confused:

Also, if you compare brands of tires, the most white/grey type Jaco's have more seams in the rear tires, often creating the illusion of a softer tire, but might be reacting like a harder tire due to the seams...

Great tires.... I have been running white LR Grey RR pink LF and black RF seems to be good.

Jacos qualify 1,2,3 at Marshalls in 10.5 set new track record also,

any of them cars running a mamba?

was any running in 13.5 when they posted on the tm thread!

good job cutter1....what compound did you run with Jaco there?? could be good for other racer who plan to race there!

Pace

i believe all three of use ran the same compounds yellow left front, black right front, white left rear, and either a yellow or white right rear, right now shadow(dirk) has the record, my car was good just never got a clean run
been running Jaco's all year and have been very happy with these tires

Cutter has the compounds right except I switched to a gray right front for the second round last night when the record was set.i believe all three of use ran the same compounds yellow left front, black right front, white left rear, and either a yellow or white right rear, right now shadow(dirk) has the record, my car was good just never got a clean run

good job guy's!!

i never have run a yellow....how thi tire feel on the track?? can you compare this tire to a white, green??s

Pace

The yellow fits right in between the white and the gray. This isn't the yellow of years past where it was the softest tire out there.

thanks shadow!

Pace

I dont post much but i will try to help here. if you need to compare foams so you can relate to other tires your friends may be running. jaco yellow is the white of old days and is close to the bsr pearl of today. At the oval masters this year i ran yellows on the left/white rr and a black rf in 10.5. in the last quallifier on sat i switched to soft pinks on the left/ pink rr and purple rf. you need to soften up side springs (take angle out) with pinks and purples because you will loose side bite but gain forward bite like Rocket stated in a earlier post. both tire combos will work but each takes a little different setup. pinks and purples sem to be easier for me due to the fact that tire wear is a lot less compared to yellows whites and green. another combo that seems to work is three greens and a black rf. FINE TUNE

isnt a white(duro 25) softer then a yellow(duro 30ish)?

I've been having a problem getting a white on the LR to stick to the track at Turn 4. I'm thinking it has to do with the multiple glue lines in the white rears making the tire act harder.
Has anyone tried the aqua rears?

isnt a white(duro 25) softer then a yellow(duro 30ish)?


EXACTLY TOO MANY PEOPLE HAVE THIS WRONG FROM OLD COMPOUNDS!

Yellow is harder than white in Jaco. http://discountrctires.com/ look here and you will see and then you can stop running your tires backwards..lmao

Brian you are right...

White 25
Green 30ish
Yellow 30
Grey 35
Black 40ish

Soft Pink 25
Pink 30
XX Pink 35
Lilac 38ish
Purple 40ish

isnt a white(duro 25) softer then a yellow(duro 30ish)?

I think sometimes it varies based on the batch LOL I felt Greg's tires at Ovalmasters, and the white RR was firmer than the yellow LR. So either the yellows were soft, or the white was firm.

How do the Jaco synthetic tires stack up against BSR whites, pearls, silver/grays, etc...? Is the wear the same? What would be the main reason to run the synthetics over the pinks and purple?

Bill

I think the wear and traction are the same for the whites and pearls in BSR. You just get more grip then with pinks and purple. But then again iyt all in your set up.

your setup can be more forgiving with a exotic compund, but the down side is more tire wear

Ok, struggled all day with the pinks and purple combination... our track is 169' runline, carpet is old ozite and not high bite, groove is worked in pretty good and I'm running the R5. Car is setup with 5.2mm front and 5.8mm back, tires were LF pk, LR soft pk, RR pk, RF purple, Left side cut at 2.14 right side cut at 2.12.

Noticed that after the runs there was very little tire wear with hardly any tire dust under the body. Car would just bog completely down in the turns and then launch off the turn down the straights. I was running my wedge at about 10.5 LR.

It handled good but just felt like it was to down in the carpet. I ended up going back to the BSR exotics that I had been running and picked up 2 laps and was only back 3 seconds from the leader by the end of 3 runs, and ran the fastest lap of the day.

What do I have to do to get up to speed with these tires? I really like the tires but I just don't have setup knowledge to get them fast. Maybe I need to switch compounds, run a lot less wedge ???? I know that setup is a huge deal but was hoping to get some help from you guys.

Bill

did you change your rear trac width when you changed tires? Jaco has different off sets then bsr

I left it the same when I went back to the BSR's and the car was up on top of the carpet and fast.. I'm using Sean's Minnreg setup and assumed he was running Jaco tires... didn't say. The setup did mention LR tire width 1.90", wasn't sure what that meant.

What suggestions do you have on the rear?

Bill

That means he cut the tire width down to 1.90 inches.

That means he cut the tire width down to 1.90 inches.

inside or outside edge or does it matter?

Bill

always cut the inside of the tire, "closest to the pod. 2nd make sure you have the same track width as his set up. You might want to shot sean a email or pm because i dont think he runs really hard tires like in the 40's and maybe even a 50 on the right front. This will free the car up a bunch with harder tires

Thanks for the advice, what's the best way to cut the tire? Never done that before is it foam only or foam and rim? Here's a quote from Sean on the 10R5 thread...

I should note that I prefer to run hard tires. Also I only run a couple of times per year so my set up is always geared toward very high bite surfaces like MinnReg and the Snowbirds.

The durometer numbers I prefer to run are RF 50+ LF at least 40 LR 35-40 RR 40. These numbers are from my personal durometer.


Bill

put the tire on the truer and cut it with an x-acto knif when the tire spin....

WLMAYE what class are you running?? pink and purple are working in speed class like 10.5 and lower

Pace

WLMAYE what class are you running?? pink and purple are working in speed class like 10.5 and lower

Pace

13.5 COT, and I think you're right they seem to work in the 10.5 and 7.5 but struggle in 13.5.

Bill

for 13.5 COT you should go with a black right front, white left front, and 2 white in the rear or maybe a grey on right rear if the track have more bite!

Pace

What about size and ride height? Our track is fairly bumpy and so about 5mm is as low as you want to go. With the pinks and purples I started them at 2.14.

Bill

They no longer make the white fronts. You would have to go with a yellow LF.

or a green on left front should work too!!

for ride height go low as you can...but make sure you chassis doesn't rub the carpet!! and for tire size for club race i start mine at 2.20...because for club race the bite is not high like big race....for big race i start lower....it depend how high the bite is!!

Pace

like i say for club race i start at 2.20...after some pratice run the size was lower...so before the race start i retrue them and put the stagger i want! so when the race start my tire are around 2.16-2.15...

hope this help!
