I need some help buying some wheels and tires. I bought my Gt second hand recently and I want to get some new wheels for it. It has 245 45's in the front on 17x9's. the back tires are 275 40's on 17x9 wheels. the tires in the back do not need replacing but the front tires do. the front wheels are also the ones I want to replace. So my question is... can I replace the front wheels and instead of 245s put 275s on the 17x9. Also (sorry this is a lot) can I put a bigger tire than 275 on 17x9 wheels? Thanks.
