Iv read on here alot about tire sizes but i figured if i gave exact stats maybe some one knows an exact answer.. its a 2001 civic Sedan LX and my new rims are 18" by 7.5 and a +42 Offset ..I havn't lowered it and i have a lip kit to go on....what tire size is the best without rubbing? thanxs for any help you may give me...

I have 215/40/ 18 tires on my car i have a coupe. i think that a 35 series tire is too thin of a side wall.

if you havent lowered it at all, i cant imagine you will run into any problems with any tire size, so long as you dont put 40" swamp boggers on. I have a friend with either 18's or 19's on his civic, without being lowered, and he looks like he has plenty of clearance.

but then again i can be completely wrong on this. lol.

mines r 215/35r/18
that .5" makes a big difference compared to my 7" offset on mah old rims.. i didnt think it was going to be a problem but thank god i had the camber kit.. if u dont have one u might have to roll the fender lip in.. i didnt roll it because i dont like the idea of bending anything lol...

Yah Pichy I cant see how you can run 18's with 215/35r/18 on Boston area roads lol you must be really careful hah..

Let me know if you ever decide to sell that Hybrid deck spoiler haha

pichy thats hot. and to the op, you can always get the fenders rolled (shaved). it doesnt even look that hard to diy. just cut off the metal hanging in there.

i bought some springs with a 1.5 inch drop so if i go 225 40 18 will that rub at all i don't want any rubbing at all but im not lowering it to much and i want the wheel well to be filled up and i think 215 35 will not fill the wheel well enough does anyone have a side shot of 215 35 and 225 with a subtle drop?

I wouldnt cut it, I'd roll it. There is a special tool that attached to your wheel studs. Here is a picture:

well ive seen guys do it with a cutting tool to ferraris and such lol. but you could still tell up close that it was done by hand cause of the not so perfect line.but who would really notice with the tire on anyway

 
Rep Power: 339

the problem with cutting is that you ill weaken the **** out of that fender.. if it ever hits you will see that fender bend like paper... if you are so worried about it the best way is to roll it.. or if you are like me that i do not want to roll or bend the fender lip get the camber kit.. 1.5 drop is not alot i dont think you will have a problem but i haven't witness it.. i dont know what drop i have since i dont remember the stock hight.. if someone knows it let me know and ill measure mine.. i have tein ss for suspencion

well ive decided on 215 40 18 or 215 35 18, the 215 35 18's are alot cheaper and easier to get so what do yous think i should get?

You're asking the completely wrong question. How do you not even consider the fact that your speedometer/odometer will be off if you go with the wrong tire size? With an 18 inch wheel, you should have a 215/35/18 tire to keep the same rolling diameter.

This is the third time I've posted this in 20 minutes, it's stressing me out a little......

so with 18" wheels its impossible to go with 215/40/18s?? I was thinking about that after everyone said 18s give you a rough ride. I dont care much about rolling diamater I might be off a few clicks that okay but is it possible?? How much will the fender be a problem?

 
Rep Power: 0

its not impossible itll just mess up your speedometer reading by a bit

I have an 01 Civic LX sedan 4dr and ive got some 17 X 7 Konig Feathers on the way with Nexen n3000 215/45/r17 comin with them! i had some people say stuff bout gettin them aligned and checkin the camber and was wonderin if i really need to do that with just 17"s or what some help would be nice!
By the way this f***in keyboard im typin on sucks!

 
Rep Power: 277

It depends on how much your camber is off when you change the suspension. If you're not changing the suspension at all then you shouldn't need to worry anything about a camber kit nor alignment, but if you're dropping it more than an inch then I'd recommend both.

Aslong as you dont lower it by over about a half inch you probably could go 40s with 18s. Just your speed would be a little over what your speedo reads but you can get that adjusted correct?

im rollin on 225/40-18's and my speedo is right on. No problem at all.

 
Rep Power: 232

i wouldnt roll it, i would cut it. sure the fender may be a little weaker afterwards, but i have heard some horror stories with rolling, if the guy doesn't know what the hell he's doing it is way to easy to begin cracking the paint, itll just start splitting, as the well surface area would increase, paint doesnt stretch like metal.

BTW,

With a 215/40/18 tire,

your speedometer will barely be affected.

Stock - 60 mph (100km/h)
215/40/18 - 59.2 mph (98.7 km/h)

So, bassically not much of a difference to worry about.

Unless you need to do EXACTLY 60 IN A 60!!

if you drop 1.5 inches and add a camber kit for the rear you will have to roll those fenders for sure. should be ok in the front... it will be close

 
Rep Power: 277

Not for sure. I'm dropped more than 1.5 all around with 18s and didn't roll anything. The only time it hits the fender is when I got people in the back and hit a bump.
