Replying to: tonyguy2000 (May 11, 2006 9:37 pm) Reasons for not doing it: 1. Technically a 225/40 should be run on a rim width of 7"-8", so you'd be outside spec on the rears 2. 225/40-18 (front) gives you an outside diameter of 25"; 255/40-18 (rear) gives you an OD of 26.1" - your suspension is set up for this 1" difference, even with the 17" wheels (though the difference there is more like .75"), and running the shorter, not just narrower, rubber in the back will make a dent in driving characteristics 3. Least important, but still annoying, it will look somewhat like you are running on spare tires in the back - it will look silly. The staggered set-up works. The car has been designed that way. I suggest knuckling under and living with a tire purchase every 15-17K miles if you're dainty, and 10-14K miles if you're actually driving the car! I get new rubber every 13K miles on average. Based on sheer driving pleasure, it's worth it. Well worth it.

Replying to: tonyguy2000 (May 12, 2006 1:06 pm) Another thought popped in here: the offset on the 8.5" rears, in order to carry the 255mm rubber without sticking out of the wells, is likely greater than the fronts. If too much moreso than the fronts, the tires will rub inside the wells at full crank. OTOH, if too little, the rims up front might actually stick out of the wells just a touch. Gives that oh-so-sophistcated air of an '84 Camaro from Compton. Mmmmm, tasty! ;-] |

Replying to: tonyguy2000 (May 11, 2006 9:37 pm) actually the answer is yes & no. If you have staggered tires (the tires/rims in the rear are LARGER than the tires/rims in the front) then you CAMMOT rotate staggered tires. You need to keep an eye on your tire pressure(s) AND you should (read: recommendation) perform an alignment at a minimum of 2X per year. HOWEVER, you could mount a front tire on a rear size rim BUT it won't feel or drive right and you might get some rubbing at the fender/wheel well housing) or the brake caliper might touch the inside of the rim (NOT what you want to happen). The idea of staggered tires is that it lends to better performance and if you paid for the 18' tire package why would you want to change it? Stick to keeping the tires inflated to the proper level & the front end in alignment and you should have NO problem. Also, don't take the car to a jiffy-boob or a Midas for an alignment (or maintenance for that matter). Take it to the dealer - they have the right equiptment and the know how. You spend a lot of $$ for a premium car, don't let just any idiot work on it. That's like buying a million dollar home and furnishing it with IKEA crap! Spend the money & get it done right. Remember, you get what you pay for! |

| I just purchased an 06 Is 250 and i wanna find some bad ass rims for it. Im new to the world of purchasing after market things so I was wondering what bad ass rims are out there that would look good on a black w/black int. IS? I kinda wanna go darker rims. But i am looking for suggestions. Also what do y'all think of the G-Spider rims from lexus? | |

Replying to: razo250 (May 11, 2006 10:28 pm)  SSR GT7 If you want to go with a dark insert, at least do it with a forged, lightweight wheel. These come in at about 20lbs, which ain't too shabby for an 18"x9. Just remember, real wheels have five spokes and more than seven basically screams either "juvenile pimp" or "geriatric poseur" in a loud, high-pitched whiny voice. IMNSHO, of course... }-]
