Default 17x8 all around?

This isnt to buy ebay wheels

I was looking at a few sets of BBS wheels (namely the stockers for an STi). They have 48mm offset. Is there any reason I cant use a 17x8 wheel on all 4 corners? 8" wide wheels are good for 215 and 245 tires. So I would think it could work. yes? no?

looks good, but it doesn't perform as well as staggered

Even tho the tires are staggered? Does a wider tire drive the tire to be wider? WHat I mean, is a 215 wider on an 8" wheel than it is on a 7" wheel?

yup even tires are staggered, if you do some search on this forum, there are a lot of discussions about this

I know both wheel and tire are staggered. But on an 8" wheel I could fit both a 215 (for the front) and a 245 (for the rear) so the tires would be staggered. I always figured the wheels were staggered simply to save on material and weight but it was really the tires that mattered.

Incorrect, 215/245 on 8" rims are different than 215/245 on 7.5" and 9" rims. A wider rim gives better performance while a skinnier rim gives better ride comfort. Mixing the two does not give optimal results. Better than no stagger at all but it is a noticeable compromise as far as performance is concerned.

Read this to get a better understanding of rim width vs. tire size.

STi wheels on s2k has been done....I've seen it here.

Just make sure you buy +05 rims...the 04's are 17x7.5 and 5x100.

There seems to be some "not quite correct" imformation given here. I'll try to explain.......

Using a narrower or wider rim does not change the width of the contact patch of a given tire UNLESS you don't compensate the pressure as you should. If you use a narrower rim than recommended for a given size of tire, you are pulling in the bead. Therefore, you need to decrease tire pressure accordingly to compensate for this. Of course, this will give you a slightly mushier ride and softer lateral tire stability. If you use a wider than recommended rim for a given size of tire, you are pulling the bead out. Therefore, you need to increase tire pressure to equalize the pressure across the width of the tread. Of course, this will give you a slightly firmer ride and a stiffer lateral tire stability. Not doing this will still not alter the width of contact patch of the tire. All it does it to make for a contact patch that doesn't apply an ideal amount of pressure on the ground, across the tire's contact patch.

I'm not sure what the exact bolt pattern of an STI is, but if it's 5 X 100 as stated, it will NOT work on an S2000. The S2000 is 5 X 114.3

thank you xviper. I stand corrected. Tire pressure can be used to overcome some of the short comings of staggered tires on same size rims. But, as you have listed, some performance is given up.
