Does anyone run 18X8 KMC Rockstar wheel on their MCS?
I saw some on a MCS and want the same look. The wheels are 18X8 with 215/35/18 tires.

Please let me know if you have run this set up and did you have to make any mods due to rubbing.

 

215/40-18 barley fit over a 18x7 wheel, you want 215/35-18 over a 18x8 wheel!!! What look are you going for "Rubber Bands Over Wheels" look???

It all really depends on the "off set" of the wheels. But with an 8' the 215/35 tire size is the most likely to fit under the wheel well. Also what MSC, R53 or R56?

 

I am running a 18"x8" set up with 215/35 on them. Love the way they look. But you can get that info off of my signature....

No rubbing at all. As for the offset I am not sure as this is the only wheel that Sparco offers in the Assetto Gara.

 

Note: a 215/35-18 has the identical overal diameter as a 205/45-17 (23.9"), this is why I chose the 215/35-18 tire size. Obviously the width is increased but the offset moves the extra width away from the car, pushing the lip of the wheel almost to the edge of the fender. Looks sweet IMO! Also, the weight of my old Crown Spoke and the Conti SSR 2 205/45-17 set up was almost 2 pounds heavier than my Sparco Assetto 215-35-18 set up!

 

thanks

Check with the tire manufacturer to see what rim widths they recommend for particular size tires. You really do NOT want to put a tire on a rim that's outside the acceptable range for that tire. It will not perform properly and you risk having the tire unseat itself and instantly deflating during cornering, emergency manuevers, etc.

Besides, whether a 215/35 is on a 7" or an 8" wide wheel really isn't going to make a difference look-wise.

Also consider that while you might think a 35 profile tire looks cool, it's going to handle worse and be far more susceptable to damage from potholes and debris and the such. I'm running 40's and drive in Northern California where the roads are still in pretty decent shape and sometimes I wish I was running 45's on 17's.

 

The cool part about visiting a site like Tire Rack is that they have tons of good info about tire sizes and the recommended wheel width for a particular tire width, for example: http://www.tirerack.com/tires/tires....za+RE760+Sport

A 215/35 shows that a applicable wheel width range is from 7-8.5. This is the range deemed safe for a tire with a cross section of 215.

Marinb is right. Keeping the cross section of the tire within the specs of a given range of acceptable wheel widths is key to safety.

I will also agree with Marinb that a lower profile tire exposes the wheel to greater possibilities of damage.

Whether or not a lower profile tire makes your car handle worse is a matter of opinion as there are many factors to consider. The type (A/S, summer, snow) of tire can have different compounds and create different traction concerns based on temperature. Tire compounds very drastically from A/S to summer tires. Tread design is another factor as is selecting a 'good' rated tire over a 'best' rated tire.

I chose a high performance tire as I wanted great traction in dry and wet, and a tire that didn't need a lot of heat to produce a good bite. I also wanted a similar ride to my old Conti's. Mileage was not of concern. Your particular needs will be different, and therefore consider all your options before you decide on a final tire. I purchased two very different tires from Discount Tire (and returned them within 100 miles) before I found what I wanted.

If you have any questions please let me know.
