Hello! My first post.

I just purchased a 99 Civic EX Coupe. I want to make a semi-sleeper out of it.
In a few days the car is getting a new I/H/E, also thinking of a cam. I do want some nice tires and rims on it. The question is what is the biggest size tire and rim combo to go with to keep it towards the performance side of the line? Thank you.

 

15 optimal....16 if you want a lil show with that go

 

If you want to stay semi-sleeper than you get stock rims.

 

If you opt for 15's, then you could maybe find a set of 99-00 Si wheels or a set of 94-95 GSR wheels. For tires, you could mate them with a set of 205/50/15's

Personally, I like the way 16's look on a civic. Especially with a polished lip. Something along the lines of a black wheel with a polished lip. You'd want to use a set of 205/45/16 tires to go with it.

 

This isn't really sleeper, but you could lift that thing up on some 40" rims with some monster truck tires. Anyone ever heard a Monster-rice before?

Anyway, I got 15" rims with 205/50/15 tires. Looks pretty good and isn't oversized. 15" rims are cheaper, too.

 

remember itll look silly with new rims if u dont lower it

 

Rip of the EX badge and slap on an HX one.

 

Thanks for the imput so far. I like the idea of takeing the ex badge off and replaceing it with the hx badge.

 

17" rims sucks in the snow. either that or my tires blow. Good thing i kept the old stock ones.....next winter they go on .......

 

It also depends on what you want to use it for. The only thing I can imagine a sleeper is useful for is on the street (good: avoiding catching the attention of cops, bad: street racing). If that's the case, you're essentially wanting to improve straight line acceleration (as opposed to autox, track, etc). If that's the case, you're probably better off get light weight 14" HX rims with the appropriate rubber. The smaller/lighter rim will be better for acceleration.

If you want a little (mild) bling for the sleeper, like it was said go with 99-00 Si OEM 15" rims. With just an I/H/E setup, you're not gonna run out of grip, so go with the stock size tires for that Si rim: 195/55/15 and get some high performance street tire. The smaller tire reduces weight (better acceleration) and improve fuel economy.

BTW... anything you do will be mild performance gains with that SOHC engine until you go forced induction, internal work, and/or nitrous.
