meph137 Posted February 3, 2009 Share Posted February 3, 2009 Hey all, currently I have potenza's on in 235/40/17 on the front and 255/40/17 on the rear, I'm thinking of getting Eagle F1 GSD3's but I can only find different aspect ratio tyres. I've found 235/45/17 for the front so thats a 5% increase in aspect ratio, is this gonna cause me an issue? I've found the same size rears so thats fine. Any advice on whether its better to go lower or higher? Lower I guess is stiffer, more road noise but better handling?? Cheers! Link to comment Share on other sites More sharing options...
Scooter Posted February 3, 2009 Share Posted February 3, 2009 235/45/17 is the correct size for standard wheels....... The newer tyres will be closer to the total rolling radius (of the rears) than the current ones. Link to comment Share on other sites More sharing options...
Jake Posted February 3, 2009 Share Posted February 3, 2009 You should be on 245/45/17 anyway. Your rear 255/40/17 are correct already. Link to comment Share on other sites More sharing options...
dr_jekyll Posted February 3, 2009 Share Posted February 3, 2009 a 235/45/17 will be closer to having the same rolling radious as the 255/40/17 as th 40 is a percentage of the overall width . Link to comment Share on other sites More sharing options...
