Better to have stickier tires up front or in rear? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

nickmerronesucks · 03-22-2016, 12:52 PM

I recently bought two GT radial 255/35s cheap because i needed two rears. well I would like to ditch the stretched front tires and get another set of 255/35's.

I've been looking into grippy tires such as the hankook RS-3, Star specs, R888, Etc

Would it benefit me mounting those on the front or the back? I figure more grip up front would be nice, but would it benefit me more in the back? I plan to run the Gt radials until they are worn.

Do you want oversteer, or understeer?

my advise would be to try to sell those GT radials and get a full set of tires.

I tried different front and rear. It caused the TCS to activate. Very very annoying!

8R6 · 03-22-2016, 01:27 PM

both front and rear.

I am currently running staggered tires and different brands. No issues.

Blah.. unfortunately A set of four isn't really in the budget right now as I still need to hit the dyno, and do some other things.

Interesting. Matching UTQG?

225/45 Michelin Pilot Sport A/S+ front 245/40 Nitto Motivo rear. Dangerous! Could not even go the speed limit.

For comparison, 500 UTQG front 560 UTQG rear.

What is UTQG?

I am running hankook Ventus noble 12? 225/40 front, and The GT radial 255/35 Rear.

No issues. Have no TPMS installed if that could help.

UTQG = Uniform tire quality grading. Or basically tire softness/hardness. The lower the number, the softer (stickier) the tire and shorter the life. Your tires are probably close enough in spec to not cause a problem. I don't think it will be the same for the RS3 and gt. Good luck.

Unless your tire pressure is out of wack, tpms will not matter.

Oh Okay i understand now. So The sticky ones may cause an issue?

Better tires in the rear - always.

In 95% of normal driving situations, it is slightly better to have the better handling tires in the front.
but for the 5% of the time that it can KILL YOU, you need better grip in the rear.
Unless you LIKE to have your rear end come around in panic braking situations....

while I basically agree with this(putting better tires in rear), its typically because 95% of the population throttle-lifts mid corner, causing the rear end to come around. And 95% of the population doesn't know what to do when that happens, and so 95% of them crash/spin out.

Better tires up front won't cause the rear end to come around unless you are turning, and most panic braking is in a straight line.

Even with "good tires", you can still throttle-lift oversteer the car though.
