Jim, I disagree, a 255 will fit on a 7.5 no problem. You said a 265 wouldn't even fit on a 7.5, and that is definately not true! And the tires will not "pop off"! Where did you get that logic? I am an aggressive driver!! The Yok 265's offer a lot more grip that the stock Po 225's. If they didn't rub under high corning loads, I would keep them! The only reason I posted this is to let others know not to get 265/35/18's unless they don't mind modifying their wheelwells a little.
Whoever said "you should shoot 'em" is just an idiot! I'm going to shoot someone for a mistake that they admitted? Get real!!!!!!!!

Is your car lowered?

I've seen S2000s running 265/35 18s and 275/40 17s being lowere about an inch and having no rubbing problems.

Are you running 7.5"s all around? If so...why?

Do you have a beef with Jim or something? First you directed this to him. Then you changed and said you just wanted to let others know...

 

Yes, I am running 7.5's all around because that is the size available in the wheel that I wanted. I do not have a beef with Jim, just wanted to point out that a 265 WILL fit on a 7.5 when he said it wouldn't. My car is not lowered.

 

This is only semi-related. Does anyone run 245/40/18s? The reason I ask is cuz the rear always wears down faster meaning the rear will look like it sags when the rear tires are wore down. So by going to a tall wheel the rear will always be slightly higher or at least flat with the fronts. What do you guy think?

TIRE WIDTH
To accurately measure the width of a tire, the tire must be mounted on a rim. Since a tire's section width is larger if the tire is mounted on a wide rim, and smaller if it is mounted on a narrow rim, each tire is measured on a specific rim width.

For example: For tires with aspect ratios from 80 to 50, the measuring rim, also called the design rim, is specified to be 70% of the section width. For tires with aspect ratio less than 50, the measuring rim is 85% of the section width.



RIM WIDTH
Correct rim width ensures flex at the designed flex point in a tire sidewall for optimum tire performance.

If the rim is too narrow, the flex point moves toward the shoulder area, creating heat buildup in the shoulder which reduces tire life and could result in failure.

If the rim is too wide, the flex point moves towards the rim area, causing heat buildup in the lower sidewall which reduces tire life and could result in failure.




Within the acceptable range of rim widths, one can select wider or narrower rims than the measuring rim. Selection of a wider rim, from within the approved range, (T & RA tables) stiffens the sidewall and improves handling at the expense of handling. If carried to extreme, either too narrow or too wide of a rim, can result in uneven tread/pavement contact pressure causing uneven wear and potentially reduced traction, or increased vulnerability to bead dis-lodgement. Always check with your Dunlop dealer for permissible rim width options.

SOCAL28,
Do you have your rear suspension modified [coilovers] and do your 255's ever rub?

 

Yes, I do have coilovers (stated in my signature) and I'm about 1.5" lower.
And also yes, I did rub in rear and I still rub in the front on occasion.
My rear remedy can be found here...

BTW, people CAN use 265/35-18 tires for S2000 rears, it just depends on the rims width size and offset.

 

meriggi,

I think you have more than one problem that you'll have to deal with. First of all, 7.5" all around is going to make your car more prone to oversteer, since our car is designed from the factory to have staggered setup. Sticking wide tires on skinny rims means that the contact patch will much less than what it actually indicates.

Secondly, since you said that your car is not lowered and it still rubs, your offsets are definitely too low. I would suggest you to dump those rims and get some that do fit. 265/35/18 tires will fit our cars perfectly if they are mounted on rims that fit our cars.
