I am stretching a 255/40/17 RA1 on a 17X9.5 wheel and it works pretty well. I'm also interested to know how the 275's would fit. I would personally stick with 255 if the wheel is only 17X9.

I run 275's on my 18x9 front wheels, no problem. Not even a "stuffing".

Careful the metal tab for the front liners doesn't cut the tire. Possibly okay if you are running very stiff suspension and at least -3* camber, but I doubt it. Let us know how they fit and work.
I have 255/40/17 with 4 OEM rear 17 x 8.5J +65 on my 100% stock S2000, but they never rub

now also running non-staggered 245/40/17 with 17 x 9J +55, very minimal rubbing on the sidewalls only, mostly happens on canyon runs

There are many variables listed above including Rims/Offsets/Rubber Manufacturer...

So, for a noob with (3) track days using AP2 rims....

Is 235-45-17 Front / 255-40-17 Rear Toyo RA-1 as Balanced as factory or is there a better combination for track days?

Oh, I have a Comptech adjustable swaybay still in box. If this alters the Toyo RA-1 selection, please let me know...

Thanks for the help...

Nope I had them on my car and they didn't rub they were just wide as hell. I took them on the track and was really disappointed. I didn't have my car lowered so with 275's in the rear and 245's in the front My car looked like a top fuel dragster. Needless to say all the weight of the car was transfered to the front and my perfect 50/50 handling that the s2000 is famous for was gone. Waste of time, money, and rubber. Unless you are lowered that setup will be a disaster. I suggest lowering your car and running stock rims and tires you will get faster times.

SD-IMPORTS:

What kind od suspension were you running? 235/255 has shown some good times......245/275 I would think more rubber the faster?!?!

Ry, offset of CE28N's are different and not optimal like yours. Poster has CE28N/s.

Uhm the question was about stretching the tire not rubbing granted I used the wrong word in my reply.

is there a point where too much rubber becomes a negative?

So you think that 245 on a 17 x7 1/2 ce28n is gonna not clear the front fenders even if I roll the tabs?
