I'm doing something a little different on my 94 Q45T

17x9 +25 in the front with 245/45/17 I was origionally using 255/45/17s, but the slight rub over highway dips annoyed me. It rubbed on the outside lip on the highway dips only (very slight) did not cause any tire damage just a fresh mark. I am running snows right now, but I am very hopeful that the 245/45s cure the rub, when I switch back to summer rubber.

Rear18x9 +38 with 275/35/18s I never heard or saw any signs of rear rub

No rolloing was needed at all and the stance is very niceI believe my diameter has dropped from 26.0 to 25.7 diameter both f/R, which is only about 1% difference. This setup was extremely affordable front wheels tires.com closeout Fondmetal 9a $95 shipped rear wheels fondmetal 9a tires.com closeout 108.01 shipped + about $210 for all 4 slightly used high performance tires +30 for custom machined front hub rings and + $70 to have the rear center bores lathed to 66.06=$716.02+ valve stems and lug nut is about $750 total and I believe there is no rub at all, but I'll have to follow up to be 100% sure. I also have the exact same setup on my S14 except with 245/40/17 front and 285/30/18 rear also I believe no roll no rub (again she is currently on snows) this setup went from 25.0 diameter to 24.7 both f/r...only about 1% speedo error

Picked up my Q from getting fenders rolled. Talk about a smooth job! It's nice to have connections, cost to me: $0. No more rub, the owner of the shop had my car parked next to his newer S-class with 22's and his dad's Deville on 20's. I wished I had a camera, it looked cool, 3 pimpin' black luxury cars from 3 different continents all parked angled in a huge warehouse. He was like "your suspension is STIFF!", I was like "really?" I guess it is a bit stiff, but it's awesome on the fwy and doesn't bother me, the wife, or any passengers I have. Everyone says it rides good, it's just sporty feeling.

Woo-wee, I'm almost finished with this car!

You need to be at ~35mm on the front in that width.

There are slight variations between one wheel manufacturers offset calculations and the next. The same goes for tires. The fronts have seen plenty of street time with 17x9 +25 and 255/45/17s there was slight rubbing over high speed dips only not enough to damage the tire. I don't think that the 245/45/17s will rub at all, but I will follow up with pictures and info on rubing or not rubbing. Also my car is not lowered, so that may explain why I don't need (hopefully)+35 offset to avoid rub

245/45-17 too short. 255/45-17 is the correct size. Increaseing load carrying capacity beyond OEM minimum specified rating of 95 will bear dividends in handling, braking, ride and wear.

If there is rubbing, the offset is WRONG. Why you need to be +35mm - +40mm with 18x9 on a G50.

Very nice looking car by the way!

I know the offset is wrong, but replacing 2 tires is less expensize than 4 wheels, not to mention I love the flush look that the WRONG offset gives me. As for load rating conti contact 2s Size: 245/45YR17Serv. Desc: 99YLoad Rating XLshould sufficeAnd tirerack recommends 275/35/18s as a rear tires on 18x9 (with lower load ratings) in the same exact diameter, so I'm not sure what the big deal is.

ASA AR1Finish: Chrome Plated Bolt Pattern: 5-114

17x7 $279 each



17x9 Optional Rear Orig. Price: $309 each$199 Closeout tirerack recommended Recommended Tire Sizes:235/45-17 front255/40-17 Optional Rear so apparently tirerack thinks the 235-45-17 isn't too short

The narrower tire with 0.15 inch shorter sidewall did cure the rub and I couldn't be happier with my WRONG offset.

According to tirerack these are the recommended 17 inch sizes, so I guess we are both wrong...

Front Optional 17" 225/50-17

Rear Optional 17" 255/40-17

I don't like these sizes, but I guess 1.0 inch diff in diameter is not a huge deal, so I'm sure that 0.3 inch difference is nothing to worry about.

Looks like my 245-45-17 are closer to the dimensions of the 255-45-17 than the tires tirerack recommends

sheadee: roll your fenders, and your slight rubbing issue will be remedied. Then again, a 255 is pretty wide to be running in front imo... I usually stick to 245 at most, but that's just me. and make sure you stay within ALL manuf. suggested specs as per nico members' recommendations, or else your car will fall apart, crash, explode, vote bush for a third term, and sexually assault a nubile junior college cheerleader. Or not.. =O

Is that pic your car? looks sick!My slight rub is actually cured already by swapping out the 255-45-17 for 245-45-17s. I didn't have to do any fender rolling, which is cool, because I don't do body work, and It would suck if the paint cracked or something and I had to actually pay for labor.I appreciate fender rolling, but my preference is to stuff as much tire under the car as possible without body mods and w out rubbing.

I'll add my 2 cents (even though they may be unwanted), but mild fender rolling isn't noticable from the "outside" it's rolling the inner lip to allow for more clearance. With the right tools, good instructions and patience, a mild fender roll isn't as difficult as most would think. The problem is too many use too much force/pressure and not enough finesse'.

I'll be working on my rears once the weather gets warm enough.
