I have GT replica....bought a set of wheels and tires from 911 guy RA1s. He is knowledgeable so almost hate to question this. 245 X 45 and 225 X 50
He had 50s up front and 45 at rear. I have installed that way and just looks a little heavy up front ...Maybe it is just so different from 15s I was running. Anybody running similar set up for comment. Wheels are 7.5 front and 8.5 rear........both 16s (sorry). Thanks Terry |

Dan:
That is what the seller told me and I trust him on that ..... These look massive compared to the 245 45 15 s I had on the car. I guess I will try them as is. I pick up a lot more contact due to width so no excuses for not improving times. Thanks, Terry P.s. Wheels are 7.5 front and 8.5 rear for the other comment. Not sure how that impacts diameter but for the sake of clarification QUOTE(DanT @ Jan 3 2011, 08:07 PM)  you will find that the overall rolling circumference and diameter to be pretty close with those two sizes. |
