Tire question 14-15 inch tire upgrade SL1

MBman · 07-04-2010, 04:33 PM

can I put 185 15's on my 2002 SL1 as opposed to the 14 inch that are on there now??

Yes (needing new 15" wheels, of course

)

185/65/15 and 195/60/15 were both OEM sizes.

I was going to try 195/65/15 last time; couldn't find a decent set though. And some people go with 205s.

Your speedometer will be off. This is something that can be reprogrammed. If you go to this website put your original tire size in and what you want to go to and it will tell you the difference http://www.1010tires.com/TireSizeCalculator.asp
