I think you are right ... there will not be a middle ground on these large wheels on an M!Vinceee wrote:some LOVE them, some DISLIKE them. I dont think there is much of a middle ground for these type of wheels.

Put it on bags. hehe.
Maybe my math is getting rusty but last time I checked 18 inches and 22 inches had a 4 inch difference. Maybe your talking about the space between the tire and wheel well.Vinceee wrote:nmgoodthing: the car sits about an inch higher than the stock 18's.
Old.. lol, but young at heart I've seen WccBaller on FrshAlloy and a few others with 22's on the newer M's and it doesn't do it for me, but that is just my 2 cents worth. I do give you props for the effort and I look foward to seeing it lowered and kitted out.Vinceee wrote:CakeDaddy: What a Lynching! Ouchy LMFAOMaybe your just getting old now. There are "many" 22's on the newer M.
Well, he is probably using a much lower profile tire than usual ... that might eliminate some of the 4" difference. Since that 4" means the car would normally ride about 2" higher than stock, he must have effectively reduced the tire rolling diameter down by an inch or so.nmgoodthing wrote:Maybe my math is getting rusty but last time I checked 18 inches and 22 inches had a 4 inch difference.

Whoops! 92 is low and could be unsafe on an M. You need to have 94 or 95 or, better yet, more than that! Please talk to the place you bought them from, and ask for them to correct this - they could be liable for installing too low a load index tire on this car!Vinceee wrote:The tires state "extra load" with a 92 rating. So I think they are made for some decent weight. I think they realized what type of vehicles and rims they would fit on.
Good! That is one way to bring the load index rating up (with increased pressure, you get increased load capacity). I would never let them get below 42 psi to be sure! The ride will be rougher (you will feel every bump!), but it will be safer.Vinceee wrote:I currently keep them at around 45 PSI for more firmness and protection.
Normally, I would recommend about 36 to 38 psi to get a reasonable balance between ride comfort and load capacity on any tire (also gives you a margin of error if the gauge is wrong, or the tire drops a few psi - this is very normal over time).Vinceee wrote:With all your knowledge, what do think is the absolute best PSI for these rims?
Yup! The tire is a 245/30-22 (it is in Vincent's sig). The effective rolling diameter is probably about 27.6 to 27.9 inches.szhosain wrote:Well, he is probably using a much lower profile tire than usual ... that might eliminate some of the 4" difference.

Let's do some quick calculations..... a stock tire 245-40-18 has an OD of 25.7 while your 245-30-22 have an OD of 27.8. The differential between the stock setup and the setup you've chosen is 8.1%. I usually tell my customers to keep the OD within 1.5% of stock. That way you don't run into problems with mis-reading speedo's, handling issues, braking issues, not to mention that you put this setup on an AWD vehicle.Vinceee wrote:mrmark: Im not a big fan of 20's with this car. I dont think it fills the wheel well enough. Although I was close to dropping on Traffic star RTS deep lip 20's! I dont know why anyone does not have these on this car as of yet!

My suggestion is you need to do your RESEARCH on this set-up before chiming in as an expert.mrmark wrote:

Check back with us in 6 months and let us know how your AWD system is handling that big of a difference in OD's. My guess is that if your dealership finds out about the setup and you have issues down the road, your warrantee will be useless. Just my thoughts.....
Oh, and filling up a wheel well is more a function of the ride height, wheels width, and wheel offset.....NOT the wheel diameter. If you run a huge wheel and keep the OD close like I suggested, the fender gap actually looks bigger since the tire profile is so low. My suggestion is to gather more information on proper wheel/tire fitment prior to purchasing a setup.
FYI...in order to run the proper tire sizing, you'd have to go with a 215-25-22. To my knowledge, there are no manufacturers with that size......
Yes, but I think that as long as all four tires are the same size (i.e., no difference in rolling diameter), the ABS and VDC will not get totally unhappy.mrmark wrote:Sorry.....but still 4.1% off.
