Default 275/35/18's on 18x9.5 +35's Will they fit

I just picked up some FF3's in 18x9.5 +35 wheels for my '08 STI and need to get some tires. I've settled on the Firehawk Indy 500's and had planned on going with 265's but wondering if I can push it to 275's? I'm on stock suspension but plan to either get lowering springs or coilovers. I also ordered a fender roller to roll the fenders. I've seen a few rides with the 275's but most folks are running 265's with the 9.5's. I'm wanting the biggest meats I can fit.

I've always felt that if you need to ask questions, just play it safe. You won't notice any benefit with 275 over 265, IMO.

It may fit on stock suspension but once you get into lowering I believe you'll definitely need a roll and some camber with 265s on a +35 wheel. 275s may require the fenders to be pulled and even more camber. You could get a tire like Michelin or BFG that run wider than most other brands, if appearance is all you're after.

Idk, just my thoughts. I avoid headaches, especially when it's a simple solution.

I was told a long time ago, that with enough money anything is possible.

I would add that with enough skills, you can get by with a little less money.

If you don't have a whole lot of either, then you will be limited to what is possible.

Are you wanting your car to look "good" regardless of how it rides or are you wanting to add to the performance? I have spent a lot of money and saw others do the same just to "look" good....I've backed away from that approach some.

There are so many variables in what will fit and what will not fit as far as wheel/tire combinations are concerned. You stated that plan to lower with springs or coil overs. With a 275's, you most likely will be going to coil overs and even then you will need to do other mods. Also, all brand 265, 275 etc. don't measure out to the same width. Michelins tend to run wider than Continentals as an example. If you're are buying from a store such as Discount Tire/America's Tire, they often will mount the two different sizes for you on a wheel or two. (I've had it done a few times) That way you can see if they clear fenders, shocks, etc.

That's why I was going to go with the Firestone's. The 265 Michelin Super Sports are wider than the 275 Firehawks. I want the largest contact patch I can get without and Extreme Summer Tire. I also want a light tire to reduce rotational mass. I'm going to do coilovers and my fender roller came in the mail today. I also like the idea of having a little bit taller sidewall. The 265's are 25.3" tall and the 275's are 25.6". The stock 245/40's are 25.7". Looks are one thing but I am going for the best handling tire I can get for launching and railing corners.
