Hi,

Picking up my 350 this weekend, and my first stop is at a Discount Tire a couple miles from dealership. Having the Good Year G 614's installed. My dealership says the wheels from the factory are the same whether you're equipped with the stock tires or the upgraded Good Years. Can anyone verify this as having done the same? I'm just trying to avoid any surprises when the shop breaks down the factory tire and tells me the wheels aren't rated for 110! Thanks
 
This question has been asked and answered before. As GDRV offers optional Goodyear G614 tires ipo the Westlakes on the Solitudes and Momentums, the wheels can handle 110 psi.

Thanks Dave

I did try to search the subject first however I never found my answer.. This is good news, dealer told me the same but just wanted to hear it from an owner having first hand experience! Tim
 
If I'm not mistaken the key is ensuring you use metal stems. The wheels can handle the increased psi but not the rubber stems. Good luck and good choice!
 
This is what is stamped on my M350. I believe the rim rating ( 3960) needs to match the weight rating of the tire. I am running 110PSI in the tires. They are rated for 4080 LBS. The lions head rep confirmed that they are OK to run!

Thanks for that info Denis. I too run 110psi as I upgraded to the Goodyear g614. Who is lionhead, the wheel mfg? Thanks
 
Another thought along this line, anyone running nitrogen? If I could find a shop capable of pressuring up to 110psi with nitrogen I think I'd spring for the extra expense. I work in aviation and we service commercial jet tires with the gas, it's much more stable against pressure fluctuations due to temperature changes. Often time some main gear tires require as much as 210 psi!.
 
bertschb, While I respect your thoughts, to each their own, but I do feel it has merit..My concept is whatever can bring even a tad more piece of mind at 65 mph on a congested interstate through a metroplex, I'm all for it.
 
As I said, it doesn't hurt to add the extra bit of nitrogen. I just want folks to understand they aren't going from 0% nitrogen to 100% nitrogen. And I'm totally in favor of doing anything that adds to peace of mind! Heck, I just replaced the brand new tires on my 318RST with G614's - just for peace of mind.
