I was looking at the Continental ExtremeContact DWS tires for my '09 G37s coupe to replace the crappy stock tires. I will be driving in some light to moderate snow, so I don't want to buy snow tires exclusively.

I would like to know if anyone knew the difference (other than the height of the tire) b/w the 1st setup vs the 2nd setup:

1st: FR: 245/40/19 RR: 275/35/19

OR

2nd: FR: 245/45/19 RR: 275/40/19


Would there be any PROS/CONS with going with either setup other than the height of the tire and a difference in money?

Thanks!

 

Go with these, the tire diameter is closer to stock.
Keeping speedo accurate.

 

Thanks a lot. I appreciate the help.
