what size tires & rims (width & offset) do you have and do you get any rubbing?

i just want to know what alternate tires i can put on 18x7 or 18x7.5" rims since the "ideal" tire size 235-45r18/225-45r18 is not very common. every shop tells me somehting different AND they can't comment on the chance of rubbing in the rear wheel well. so i though you guys are the perfect bunch to ask:D

- currently picking between Enkei CDR9's or Racing Hart S7's, maybe Konig Tantrums. can't wait to get these rims on!

thanks for any info
Dennis

you might want to try http://www.discounttiresdirect.com....i bought 18" konig tantrums and they recommended I get the 235/50/18 wheels to go with. They guarantee what they say 100%

The guy at http://www.discounttiresdirect.com told me that they go out and physically measure the space of the wheel well on all different types of cars for the rims and tires they sell. I should be receiving my new rims and tires soon. I'll fill you guys in on when I put them on and let you know if I have any problems.

You might want to try to go to their wwebsite. You can call them and talk to one of the salespeople there.

Check this out about plus sizing from http://http://www.discounttiredirect.com




Plus sizing is one of the easiest ways to achieve enhanced performance and improve the appearance of your vehicle. In the example above, a 15x7 wheel with a 205/65R-15 tire is considered the O.E. (original equipment) size. Converting to a plus 1 size would mean increasing the wheel diameter by 1" (16x7.5) and selecting an appropriate tire to fit (225/55R-16). Likewise, moving to a plus 2 fitment would result in a 17x8 wheel and a 245/45R-17 tire. It is important to note that although the wheel diameter is increasing, the overall diameter of the tire remains consistent. As a matter of fact, this method typically maintains the overall diameter of the tire within +/- .04 inches. This is crucial to preserving the speedometer reading and gear ratio.

A couple of things happen with the tire to increase performance when we begin to move into plus sizes. First, the tire is wider (section width) and therefore gives us a larger footprint. Second, the sidewall becomes shorter (aspect ratio) and more rigid. The two added together give better lateral stability and increased steering response.

My wheels are: 18x7.5 45mm off set ADR GT Sport w/235/40/18.
Eibock pro springs is just the right combinations.
thanks for the feedback guys.

Voyagergone: nice rims. where u get them? i didn't expect the 235/40/18's to rub. most members seem to have chosen this size. the problem is that this wheel is almost 1" smaller in overall diameter than stock (25.4" vs. 26.3")

check out:

this causes some speedo error and INCREASED wheel gap. i'm mostly concerened about the wheel gap :D. When looking at your pics, i'm pretty sure that i have less rear gap w/ my stock tires (the top of the rear tires just barely tucks under the wheel well). so basically i'm trying to find a somewhat bigger tire that won't rub and isn't as expensive as the 235/45/18's i've found.

these tires give a wheel diaeter of 27.3"! exactly 1" too big. i think this will rub w/ prokits 1) 2cm wider & 2) 1" taller (1/2" on each side). but they will probably be fine on stock suspension. let me know how it works out for you.

I went 245/40/18.. on a 18x8 rim, and honestly my next set of tires will be 245/45/18.. you can pics in my registry.. but after having 245's.. I will never change.. I love how wide the damn things are.. makes the car look that more mean..

Pro kit will drop front and rear the same amount of appox. 1.3". You don't want to go too low with sport line if scraping is problems for some of the drive ways. V1:( :(
They drop the same front and rear 1.3"?
coz from looking at my stock springs, the front is signficantly higher then the rear, the rear is lower than the front, by like at least an inch.

Some people say the pro-kit is 0.8 in the rear, and 1.3 in the front... which kinda makes sense, because the car kinda even's out..

I just got my prokit installed a week ago, and the steering response was the first thing I noticed. It felt so much lighter and responsive than before. I was oversteering turns like mad!

I got 18X7.5's w/ 245/40/18 kumho's and +42 offsets on my wheels, and no rubbing, in fact one of the sure-bet sizes with prokits installed if you want worry-free rubbing.....

here's a look..

how do you like those tires... I had those on my rims first, and didnt have a good experience with them so I swapped them to Bridgestone S03's..

When i was a hon-duh owner, i had the kumho's and they were ahhright, but i'm not liking them so much now on my alty.

I'm not digging the road-noise with them, and the profile of the kumho's aren't what I was expecting. Thinking of going with falkens's next time, which are quieter and have a "curved" profile.

Like you, I'm also thinking going 245/45/18's on my next purchase of tires....

I don't plan on lowering my car. I will probably keep the stock suspension, being that the tire size 235/50/18 that I got is 1" bigger than the overall diameter of the stock tires. I hope there is enough room for those sized tires and hopefully I get no rubbing.'
The guys at http://www.discounttiredirect.com told me that I will not have a problem. I'm going along with what they said. If I do have problems they told me that I can send the tires and rims back for a refund or a different sized package!
