Ok here is the situation, i currently have T1-R in 235/35 and 315/25, the recommended size. They are OK tires but i would like something with a little more grip and especially something a little wider in front because my car understeer pretty bad at the track in long corners. I don't want too agressive of an alignement as i like to keep my tires for long and have them wear evenly.

Now i found that everyone seems to like the Bridgestone RE11 and it seems to be the best compromise between street and track (don't want 2 sets of wheels and don't want to drive on R compound yet, not ready).

the problem is the choice in size, with the 315/25 in the rear, all you can have is T1-R, Invo or the expensive Pilot. If i want to go with RE11, i would need to use a 305/30/19 as they don't make a 295/30.

Per tirerack, the 305/30 is 26,3" high or 792 rev/mile. To get a good matching front tire, i would need to get a 255/35 which is 26" and 801 rev (pretty close). My other option is 245/35 which is 25.8 and 807 rev (maybe this is too much of a difference?).

So, anyone is running 255/35/19 in front without rubbing? I am on PSS10 and the suspension isn't all that low, i would guess GT2 or GT3 height probably. They are about 0,5" taller than my current 235/35 T1-R but also 20mm wider..., 245 would make more sense but i am afraid with all that chewed differential talk.

i did a lot of research on the forum but not many people seem to be running this, i beleive i have found only one.

thanks a lot for any help or experience. It would suck to buy tires and not be able to run them because they rob on the suspension or the fender.

 

I'm running a 265 on a 9.5"x 18" front wheel no rub.

Links was running 255s on 19s hit him up...

 

I am running Michelin Pilot Super Sport 255's and 305's on 19" HRE's with no problems!!

 

are you guys lowered? If so, how much? are using 255/35 and 265/35? Any other mod to make it fit?

 

Sorry, I guess I should have mentioned that. I am lowered far below GT2 specs, but because of that , I had to roll the fenders (its a lot easier to do than it sounds). There are a bunch of threads on how to roll the fenders. You may not have to roll them if you are at GT2 height or higher.

 

how the &?$/& do you guys get to fit this, damn i bought a set of tires for nothing

 

245-40-18 & 335-30-18 R888 work well. Rears need rolling and fronts will rub a bit at lock (lowered car). Grip is great.

 

Par for the course. especially with aggressive offsets.

If you're really into it, you can mod the fender liner for more clearance. Hit up Sambo I think he did it on his car.

 

I did this with a heat gun and removal of the rear fender liner bracket (driver's side).

 

i will look into modifying the fender liner, i am just wondering what there is behind that "bump"

ari, you said in the PM that you rub a little when doing thight turn, i rub when i turn the steering wheel even half a turn, the bump in the liner seems to be the problem.

I'll do some more testing i guess.

 

looks like you already got the tires,but have you tried a different rear sway bar to help w/ the understeer ? might be a better solution.Also you said you did not want 2 sets of wheels,but the car will handle much better on 18's

 

well what i wanted was to try to get the same rolling diameter than the 305/30/19 and the 255/35 are much closer than the 235/35, since some people said they blew the viscous coupler of the diff with 235/35 and 305/30, i thought i would take no chance.

I eventually will roll with stock 18" for the track at some point but i still want to learn to drive with my street tire first, i feel i still have a lot to learn before i go slick or R-compound. Plus, with the 3-4 days i do a year, they would become dry before i have the time to use them all.

 

One thing that I ended up doing on my car is removing the fender liners and moving the radiator bracket forward about an inch. A little work with a heat gun on the liner can help make some more room too.

Well that's exactly what i thought i needed to do but was too afraid to do it, can you give more info? What did you do exactly, did you need to take the bumper off, it seems like it is bollted down, did you make some new hole or something.

Some details would be very nice.

thanks
