GL320 RunFlat Alternative




Growing weary of spending $2000+ for tires, I'm looking for alternatives, but find there are shockingly few options in an all-season 275/50/20, regardless if they are run flats or not - only the original Goodyears and Bridgestone Duelers (which have mixed to negative reviews).
Does anyone have EXPERIENCE (no hearsay, please) putting 275/55/20's on the GL? There are many more options in that size - wondering if the slightly larger diameter causes any problems. I know about the slight speedo error (mine already reads a bit fast anyway, so this would help). Just curious about clearances at full lock, etc.
I'm also considering just getting a set of OEM 18" or 19" GL rims and fitting something with a higher sidewall for better ride (the 20" run flats are awful). Honestly, I don't care about the run-flat option - too many trade-off in cost and ride quality - I can carry a spare or keep one in the garage!




Been wanting to drive a GL w/ADS and standard 20" tires to see how much better the ride actually is...
