Michie's makes a tire 255/55/18 vs. the oem 235/55/18. (10.4 sec wid and 29" tall). It is .6" taller and about .7" wider. Any thoughts about whether this will greatly effect anything other than, "hey, wider, taller tire?" I'm sticking with the R/T black-ed out rims.

BFG makes a similar tire in a 245/55/18, but I am reluctant to put those on my daily ride.

Any other rec's would be appreciated.... I'm only going to get about 40,000 out of the oem's, but that's not totally terrible, I guess.

Thanks

Gotta get that diablo....

 

blacked out RT rims: done by you I assume? If so what'd you use and how'd you do it?

I went with 255/55/18. fill up the wheel well a little better

 

In 2006, the Road Track Package had special black painted rims (on the inside). So nothing custom....

I hate to ask, but do you have a pic posted showing the rims/tires? I assume you don't have any other issues, which is cool. Why re-invent the wheel, right?

I replaced mine with 235/50-18 which are .93" shorter than stock 235/55-18. They changed my 0-60 time from 5.8 to 5.45 seconds. The gearing change really makes a difference in performance. I changed the computer to the correct tire size using a Superchips programmer. But when I put in the actual tire size it was still off in mph. I had to measure my speed with a GPS and figure the error, then change the tire size by the same %, and now it is spot-on. I would expect that a larger tire size will slow your acceleration slightly...

 

I agree that it will probably slow your acceleration a bit, and may hurt your gas mileage slightly (if you're at all worried about that ). I would expect it to slighly improve the ride quality - higher sidewall giving more "shock" action.

I've got the BFG 245/55/18 G-Force KDWS on my car and I am satisfied with them. Not great in the snow but better than the stockers were. They are not a snow tire and have a tighter less roll feel than the stockers (Goodyear Assurance ) on the back roads. I am not complaining about them, next time around I'd go wider though. Not sure why you say you wouldn't put them on your daily driver. Oh yeah, I special ordered them through BJ"S wholesale club for under $700 complete including taxes and road hazard/ lifetime roation and balancing. BJ's also offers the michelins, if you shop BJ"s watch for coupons in their flyer for $10 off per tire then order them.

 

Wow... great price on the BFGs. The KDWS are perfectly fine, but I need something that will work in a bit of snow and ice once in awhile. I have BFG's on my 442, but then again, that car rarely sees rain, not to mention snow or ice. The oem Michies' were pretty bad in the snow, but then again, I don't know that any tire can be a great snow tire and a great dry traction tire as well. So it's compromise time. The oem Michies are over $225 each on tirerack. Hmmm, maybe BFG's could work...

I would like to fill up the wheel well a bit, and honestly, I am usually only racing myself. I really just want to make sure whatever I put on will fit and not make the car look like my son's Hot Wheels (ie with oversized wheels and tires). That would be BAD. I am surprised that there not more options manufactured for a wider tire of similar height. I guess it's the 18 in rim size that is unusual.

As always, thanks for the info --

The Michelins would be better in the snow due to more advanced siping technology even though the BFG treadlooks slightly more aggressive. I am in CT and travel up into VT and NH, I avoid the snow when possible, only snow tires will make a big difference in my opinion, I will not go that route though I'd rather stay home.The BFG's have always gotten me to my destinations you just have to be smart with travel plans. I wouldn't worry about the BFG being too big the diff between those and the stockers isn't all that noticable and they still look very tastefull. I agree the wheel well needs to be filled a bit, I am considering a wheel spacer or maybe new rims with a different offset and lowering the car about 1 to 2 inches. Gets expensive quick!
