Just bought a set of used Rays 19 inch wheels (8in, 8.5in) for my 2008 g35 journey. I have a couple of questions. I believe the best tire specs for these would be 245/40 in front and 275/35 in back. What would be the best tires for these with balanced durability in mind? I am keeping the OEM standard all season 17in 225/55s for winter use, but still would like the new tires on the Rays wheels to last a while.

Also, what do I have to do about the TPMS on the new tires if anything? I'm not even sure where the sensor is or how it works exactly...

 

do they have the TMPS in the new wheels?

if not you can buy em and when you get your tires mounted then have em put in. if not then the worst thing that'll happen is you will have the tire pressure light on.

 

I would assume that these wheels don't. They are 19in Rays wheels off a 2005 g35 coupe. I suppose I'd have to have the dealer turn the light off then? That's really annoying.

 

i dont think the dealer can just turn it off.

to my understanding you can get a used set of TPMS sensors for 25$ each so 100$ for all 4 i might have some for sale if you are interested.

 

Which tire? Take note most 275/35/19s recommend a minimum wheel width of 9".

Tires that last longest are Grand Touring and/or All-season tires. Most, if not all, HP Summer tires will wear out faster. Since you're running staggered you won't be able to x-rotate. If the tires are directional, you will only be able to rotate L-R by unmounting, remounting the tires. Although if they're directional and assymetric (has "outside" written on the sidewall) then you can't even rotate L-R.

As for TPMS, the light can't be turned off by the dealer, but it can with some work. I recall someone mention they found a mention of it in the FSM. You can also either ignore the light, get a set of sensors, or put black tape over the light.

 

The easiest thing to do with the TPMS sensors is to move them from your stock wheels to the new wheels. The BCM can only be paired to one set of sensors anyway.

Note that the new wheels might need to get drilled to install the TPMS sensors depending what how wheel profile looks.

Once the TPMS have been removed from the stock wheels, the tire shop can install standard stems onto the stock wheels if you plan to sell them or something.

 

The TPMS is useless on after market wheels. It's a lot of hassle to put them on the new wheels. Just leave them and deal w/ the yellow light on the dash board.

 

As a follow up question, would 255/40/19 front and 285/35/19 back work on my 2008 G35 Journey. Would these be too wide? I know that the total diameter is a couple mm more than the stock 225/55/17 wheels/tires also.

 

Diameter-wise, you're well within the margin of error.

Although, IMHO, and per several manufacturer specs, they are too wide for your rims. It'll still mount, but good luck with safety issues if it comes back to haunt you.

Question though, why are you going so wide on relatively skinny wheels? They're not going to look noticeably wider stance-wise. From a performance stand-point, it's diminishing returns.

 

I have been told these Rays 19in. wheels are 8 and 8.5 inch front back from people on this site, but the existing tires on the wheels when i bought them (245 front, 275 back) sit perfectly flush with rims. Makes me believe the rims might be wider than that, and that I could go 10mm wider front and back on the tires. I'd be doing this also to provide some added protection against curb rash. I hear your point, but how can I be sure those rims are 8 and 8.5 width without getting the tires off and physically measuring them? I think I need to take them to a tire shop to get the answer...

 

Stock,the 19" rims have 225/40 and 245/40. I have an entire thread dedicated to my 275/35 and 245/35. They are perfect for these rims, 285 WILL be too wide for the rim, 275 is 100% the largest i would be comfortable driving on.

Get 275/35 though. Thats the correct profile for making the VDC work properly.

I promise they are 8 and 8.5 btw.

 

Ok, good on the 275/35 in back, but 245/40 in front, right? I believe that is the correct diameter to match stock (225/55/17), according to wheel diameter calculators. Remember, this is a 2008 g35 sedan, not 1st gen coupe...
