i got a honda civc ex 2 door and i got some 18 in momo rims when ever i go over a bump hard my back tires hit and when i turn sharp my front tires rub i just got my licens and new at all this and i dont kno what to do

 

You'll either need to roll the fenders or buy different wheels or tires.

 

Get much smaller rims. 18s are way too large, both aesthetically and physically. There are no tires to fit on those 18s to give you a stock diameter, so not only are you chewing up your tires but you're also throwing off your speedometer and odometer.

I recommend moving down to a 15" or 16" size with the proper sized tires. You can look at the FAQ up top for more info on which tire is the right fit for you. If you're lowered at all, you're going to be exacerbating the problem until you get the proper size wheels and tires.

 

He could easily run 17s, too if that's his thing.

Well, that's partially opinion. Although 18s aren't my thing, he might like the look. Also, a 215/35/18 should fit -- it's only a bit over an inch wider tire and the speed will only be off 1.9% (e.g. at 60 mph, his speedo will be reading 61.2. Yes, I used this: http://www.miata.net/garage/tirecalc.html). However, if the offset on the wheel is too small, that might be why he's rubbing.

What year Civic is it?

That depends on the year. If he has a '96 or later Civic EX, yes he could. If it's a '95 or earlier, even the smallest commonly available 17" tires - 205/40-17 - are much larger in diameter than his stock tire size.

If his tires are larger in diameter and wider than the stock tires, it's fact, not opinion. And almost certainly the cause of the rubbing.

No, not true at all. First of all, if it's a '92-95 Civic EX, it came with 175/65-14 stock size, and the 215/35-18 are 4.2 percent larger in diameter, a full inch larger in diameter as well as 40 mm in treadwidth. Even if it's a '96-00, for which it's 1.9 percent larger, the extra half inch in diameter plus the extra 30 mm in treadwidth can easily combine to cause rubbing.

As a general rule, if you want to avoid rubbing, keep the outer diameter no more than 1 percent larger than stock, and the treadwidth no more than 20 mm wider than stock. He's violating both of those rules, and doing so is almost a sure bet to cause rubbing, regardless of offset.

 

There are (were?) hundreds of 5th-gen Civics running 17s; I guess I figured there wouldn't be a problem. I know it's not a problem on 6th gens.

I guess I didn't know 18s were such a tricky fitment on Civics. Back in the day, when 17s and 18s were a big deal, I swear that a lot of people ran 18s on Civics. Maybe they just rubbed a lot. However, since I never ran anything bigger than a 15 on my Civics, I guess I just assumed (and we know what happens when you assume ).

 

Yeah people did really like to run 17s and 18s back in the day, but then again how many of them cared about their odometer or speedo? It's kind of like how people used to run massive wings on their Hondas or cut their springs. Yeah it may have looked cool and it may have been the style, but it was still at best pointless and at worst dangerous.

Kind of like running an aftermarket steering wheel in a street car and getting rid of the airbag. It may look cool but you better hope you don't rear end someone.

 

18's fit all day as long as you had the right offset and the car wasn't lowered too much. Was it the right fitment for a 92-95 civic or crx not really but peolpe get what people want!!!!!! It sounds to me that the momo wheel for one has a lower offset than what the car ask's for. Anything lower than a 40mm offset on a 7 or 7.5 wide wheel in a 18 inch wheel will have issues. i would suggest that you get a different wheel with the right offset or get a smaller wheel and tire package that will fit right and still have the look that you want!!!!
