Found out the difference between 275/60/15 and 275/50/15 Did anyone know that the 275/60 ET radials only have a 9.5 tread width?
Well I grabbed a buddies 275/50 tires last night on the way to the track and took off my 60s... After some searching online I found out that the actual tread width on a 275/60/15 is actually only 9.5in (versus a 10.5 width on a 275/50). Well long story short I pulled into a parking lot to see how they were hooking and the car dead hooked from a low rpm launch and just shy of pulled the wheels... Never made it to the track to put down some new 60' times because of a bad driveshaft... Just thought I'd share the info, I had no clue the tread width was different...

Mine are on a 10 inch rim... For some reason the car would NOT hook on them... The other thing may be weight transfer, a 28 tire sets the back up quite a bit, and since I have stock front suspension it may just be having a hard time transferring weight.

yeah for sure with any tire that will happen ... get adj qa1 fronts and the 28 will be completly diff ... your not transfering the weight ...the whole formula for going fast is to have all the pieces of the puzzle, having one and not the other you'll only go so fast

FYI just for sizing tires. The first number is the tread width in millimeters.
Take that number and mulitply by .03937 to find width in inches.
The second number is the side wall height. It is a percentage of the width. So "50" is 50% of 275 millimeters
So a 275/50/15 tire is 10.82" wide and 25.83" tall
