Question
I want to fit larger front and rear tires, but will it harm suspension geometry, if so could it be corrected, thanks for your help.

Answer
Hi John:

It won't really effect geometry so much as to alter the handling characteristics and of course, render your speedometer inaccurate.   Steering will be less precise, and stiffer, acceleration slower, and gas consumption higher.    

More modern cars will suffer problems related to the engine management system which reads information from sensors that read axle speed, and so forth.

you didn't tell me what kind of car you are working on, nor what you hoped to accomplish with the change so I really can't tell you much more about it without further information .

Good luck

Experience

I have been racing for 20 years, I have been the Central Florida SCCA Regional Championship points for 5 years running, and won the championship in my class 2 times. During my first start in the 60's I won many solo awards and the State Championship Drags. I serve as a senior instructor for SCCA, and have taught in Mercedes AMG events at Daytona, and Dodge Viper Days at Sebring International. I have been in the thick of the competition for all of my career. At one time or another I have driven race cars at speeds nearing 195 MPH. It's quite a ride !
