Default Question about tire specs + wheel sizes.

Okay so i'm pretty much a cheap ass and want to get some rims to replace my stock ones(come on now, no matter what size NO ONE likes those stock ugly ass Pacer 83B black rims...plus mine are oxidized and nasty and hubcaps are just unattractive)so basically here is the predicament.

My tires are 185-65R-15, which I suppose means they're 15 inchs but i'm not sure in what respect, diameter or what? Moving on, the rims I've been looking at are of course 15 inches in diameter but they vary in width, for example some rims are 15x6.5 inches or 15x6 inches. I've done a little bit of reading(barely any)and what I'm inferring(and could be incorrectly inferring mind you)is that the 6 inch width wheel would look more normal for my tire? I spoke with someone who said that actually the 6 inch width wheel would make the tire look slightly off and by that he meant the tire would look slightly skinnier.

Anyone who has some experience on this would be greatly experience. You don't have to preach the whole "Nothing cool is cheap, nothing cheap is cool" I know the rims won't look the best but for the money I want to get what will have the best aesthetic capacity.

Thanks.

Ok, lemme try to decode your tire size.


You mentioned stock is a 185-65R15. This is pretty simple to decode.


185 = tread width in millimeters. Your tread is 185MM wide. In inches, that's about 7.25

65 = Aspect ratio. This is the ratio of sidewall height to tread width. Your sidewall is 65% as high as your tread is wide. 120MM would be the approximate measurement.

R15 = rim diameter in inches. You have a 15" rim. Now, rim width is rarely terribly far from tread width, so you could say your rim is roughly 185mm wide too. You have a pretty standard rim for American market vehicles, a 15x7. You could find a rim in this size on just about anything spanning the mid 60's to the mid '90s, everything from pickup trucks to economy cars. All of the vehicles in my sig came stock with this size, with only my Ford having a different size now. Being that they're so common you should be able to find an aftermarket one in this size that suits you as well, and it shouldn't cost much.



If it were my car I would look into upgrading to a 15x8, or possibly a 15x9 if it will clear everything. Wider tire = better grip. You could also get away with a 16" rim without any trouble whatsoever, so long as you remove 1 inch from the sidewall height as well. Oh, and do NOT get a universal fit rim. Make sure the rim you buy is designed specifically for your car's bolt pattern. The hub of the wheel will be MUCH stronger this way, and you do not want the wheels coming off if you can help it.

I'd just stick with the stockers till you can afford something nice. $75 per rim is terribly cheap.

As for sizes. The tires will have a recommended rim size (not vice versa due to the tire height ratio).

Twidth/height (ratio)/rim size.
