Hello,

I have recently moved to Qatar from America and have shipped my 2010 Camaro SS with me. The threads on my tires are nearly gone now and I need to replace my tires before I can renew my car registration so I can drive it. The problem is that every single dealer in this country does not have the sizes im looking for:
245/45ZR20 Front
275/40ZR20 Rear
They either have one size or non at all. However I did find a dealer that had the front size in one brand and another dealer that had the rear size in another brand. Of course the threads are different also. Now I am no expert and I desperately need help with some information. Can I install new tires front and rear with different brands? also the Michellen Dealer told me that they can install 255/40ZR20 in the front and 275/40ZR20 in the rear and was very confident about it and that its fine but for some reason I dont trust what hes saying. Can I do that??

Any information will be highly appreciated.

Thank you

 

Based on the two sizes for the fronts, the 245/45 is 28.7 inches tall and 9.6 wide and the 255/40 is 28 tall and 10.2 wide. Which Michelin tire is he trying to sell you?
