First timer here

I have 18x9.5 +35 square wheels and trying to decide what size tire is best for stock suspension, I am not willing to do fender work. Eventually I will be purchasing coil-overs in the upcoming months.

I was thinking 235 40 all around.

IDK, i was also thinking about staggering the tires with 265 35 in the rear with 225 40 in the front...But! i'm pushing more towards the 235 40 all around....
Also i hear stuff about the speedometer having problems with bigger tires? What's that all about?

Help me decide! I want functionality AND looks, and when i do eventually get coil-overs i want a decent drop. what do you guys think?

245 35 is probably what you want for right now. Shouldn't go too wide on stock suspension or you'll have rubbing issues.

I would advise against a staggered set up, especially with that much of a difference (265 vs 225). 225's on a 9.5 is going to be super stretched.

You want the diameter/circumference of your new setup to be close to stock if you want your speedo to be accurate.

Im running 235/40 on 18x9.5 +30, had to shave my rear fenders because im running 0 camber in the rear.

What do I think? 9.5 wide wheels are overkill for our cars. Too much useless weight. I won't put anything smaller than a 255 tire on 9.5 wheel. I'll put a 265+ on it.
That's what I think. All show, no go right? Park hard bro.

I just put on 255/35s on my 18x9.5s i wouldnt go any smaller.. wait till you get coils then buy the proper size tire for a 9.5 in wide rim

It really depends on your purpose. Don't stagger them if you want it to drive properly. It will make the car understeer even at moderate speeds. I run 18x9.5 +38 with a 265 slick on the race car, but that car is double the stock HP. They fit but I had to pull the rear fenders even with 3+ degrees of camber. They do fit on a bone stock suspension but they'll stick way out. I ran mine on a stock BRZ for a TT event.

This car is my daily, that's IT.

Thanks for all the input guys, I'm definitely not going to stagger my tires, nor am i going to stretch my tires, atleast to the extent of the 225.

Nice setup btw GEN!

Would 245 40 rub on stock susp?
