Anyone know if I can put Yokohama Avid EnVigor's all season tires in the front and Continental DWS all season's in the rear? The reason why I am asking is because the Continental DWS all season tires do not come in the factory g37 front tire size of (225/45/19), but only has 225/40/19. I don't want to cause the speedometer to be off due to the lower profile.

Doesn't seem like there are any drawbacks in doing this since I would still be keeping the factory setup but I would like some input before I make my purchase.

 

it might wear differently, cause some odd handling, but mechanically I don't think there would be any kind of problems

 

Shouldn't cause any problem.. The handling may be strange in cornering and spirited driving. Lol

 

Has anyone ever had problems with teh inaccurate speedometer due to a different tire profile/size?

 

as long as you actually get the right sizes there should't be any inaccuracies. You just have to do some homework and make sure to get the right AR/size

 

I want the continental DWS tires so I plan to use 225/40/19 in the front and 245/40/19 in the back. So the front profile will be off by 5. Not sure if its worth throwing off the speedometer though. Would it affect anything else (ABS, LSD, etc)?

 

I'd say pick a different tire if that ones not available in the correct size. Try hankook, falken, toyo... I'd rather keep the factory profile or go a bit wider.

 

How about for the rears? Would going 245/45/19 instead of 245/40/19 cause any problems like the fronts would with speed sensors etc?

 

Really do not recommend it. The DWS is an asym design and the Yoko directional which do not play nice together. Good article off our site here Mixing Tires

 

I am pretty sure 225/40 and 245/40 will be fine on our cars and cause no issues. I mean the g35 coupe with the 19's ran those exact tire sizes as OEM tires

 

i have falken f452 in rear and envigors in front my handling feels amazing compare to when i had my oem potenza tires so IM PUZZLED
