I have a question, what if your Front Tires dont match you Rear Tires speed. Tire Size Calculator's say "Tires should stay within 3% of the orginal tire size". Tires i "Might" be getting are 3.43% Faster in the front than the Rear Tires coz i cant find Approved Tires in the correct size... My question what will happen? Will my car catch fire and burn lol?

PS: On VWVortex i was told 3-4% Is fine... true?

 

The car's traction control and ABS could be affected if the systems work by comparing revs per mile one axle to another. I have heard of customers having cars that throw on the brakes mid-curve because it thinks you are sliding or losing control, when in fact you are not. I think 4% is the limit on the TT/C4S, but not 100% sure.
