MTYQIN Posted August 15, 2013 Report Share Posted August 15, 2013 Guys, Anybody have experience running 305/30 or 305/35 on a lowered rear. Currently have 285/30 NT555 on 20x10 CS40. The FRPP FR3 suspension pkg I put in has lowering springs (1.25 inch drop). The tape measure says "looks too close for comfort." Where I am in Virginia, I can't come up with the tire anywhere to try it on. Any input/insight will be most appreciated. Thanks, Quinn Link to comment Share on other sites More sharing options...
Madlock Posted August 15, 2013 Report Share Posted August 15, 2013 You may rub only under compression but, depending upon your wheel width and the tire's ACTUAL dimensions, you're going to be riding too close for MY comfort. I'd drop to a 30 profile. Link to comment Share on other sites More sharing options...
MTYQIN Posted August 15, 2013 Author Report Share Posted August 15, 2013 Madlock, Thanks for taking the time to get back to me. I concur, 35s are too tall - 28" on a 20x10 CS40. A 305/30 specs out at 27.2'', only .5'' taller than my current 285/30. What I'm not sure about is the clearance to the wheel well lip. Your rec to go with a 30 profile is solid. Thanks. You originally from NJ? I grew up in Philly. Take it easy, shipmate. Quinn Link to comment Share on other sites More sharing options...
magnonreyes Posted September 11, 2013 Report Share Posted September 11, 2013 I want to change the tires for my 2012 gt500, I want the same rims size 19 front and 20 rear, but I would like 11 and above tire width for the rear. Any suggestions? Ivannnn Link to comment Share on other sites More sharing options...
Madlock Posted September 11, 2013 Report Share Posted September 11, 2013 The available widths of the brand you choose are going to tell you what size you'll wind up with. Above 325, you're going to drop to a 30/20 Just be prepared to go with a wider front tire too to keep the handling balance. Link to comment Share on other sites More sharing options...
Wanta13shelby Posted September 21, 2013 Report Share Posted September 21, 2013 You guys are way more educated on the tire size and clearances than I ! I don't know if this is what your asking but I have a lowered '10 and have 305/30/19 on the rear and no rubbing issues, yet. Normally it's me and my wife in the car so there is no real weight back there. However, I did fill the trunk with 3 cases of drinking water and groceries and drove home with no issue, although I was not driving aggressive at all. On a side note, the tires up front rub when I hit a bump at highway speed. 255/40/19 possibly need stiffer springs (eibach)? Link to comment Share on other sites More sharing options...
