Hey
Few weeks ago my rims got stolen off of my 2013 g37xs coupe with the 19" rims tire size 225/45r19. The other day I bought rims and tires from someone who has a 2012 g37s coupe tire size front:225/45r19 rear:245/40r19..i put these on and now the tpms light is on. I didn't realize that the back rims are diff size on the xs from s.. Is this a big problem? How can I fix it ? Thanks everyone

 

The different size shouldnt matter , Does the new wheels you bought have the tpms sensors in them I bet you this is your problem ?

 

You need to sync the TPMS modules. There's a DIY up on these boards.

 

Ye they have them..the person I bought the wheels from took them off his car because he got aftermarket wheels. I am planning on changing the tires because the ones I have one make noise. I kind of. Feel better now since the size of the rear tire won't be a problem. Do I go to the dealership to sync them?

 

Dealership will do them for you. I got mines done while getting work done. No charge for that.

 

first check if there is a TPMS. then ^ this.... and hope he did not put older TPMS in there hahaha GLWS. you really dont need them. just check pressure time to time.

 

Ye but I'm not having work don't so they will prob charge me an arm and a leg for that. Is that the only option to go tithe dealership. I assume it wouldn't cause anything bad when it comes to the 4wd. How do I check for tpms?

 

Did you not see what I wrote above.

 

Thank you

 

PS. I'd be careful with those tire sizes, they could easily cause issues with your AWD.

 

What could happen with the AWD?

 

If the tire sizes aren't within 3%, you could cause damage to the transmission and/or transfer case.

 

I'm sorry but you got the wrong person I was never banned from this site and I never asked anyone for money.

If your AWD light is lit on your dash, it could spell trouble down the road (literally). The AWD system on the G is not meant for a staggered wheel set-up. AWD coupes with the sport package (xS) come from the factory with all four tires the same size for a reason. If you continue to run a staggered set-up on your AWD G it could compromise the AWD system. There are numerous posts on this forum debating this subject. To avoid any issues, all 4 tires should be the same size. For my summer set-up, I run 245/40/19s on all four of my rims and have no issues.

 

Tire diameter is practically the same for 225/45 and 245/40. You can easily get more of a difference running tires at full tread depth and pairing it up with tires that are down to the threads.
