Need tire size recommendations...
 

I'm getting ready to buy new tires for my GMC, wheel sizes are 20x8.5 front and 20x10 rear. I'm thinking either a 275/35 or 275/40 on the front, and going back and forth between a 295/40 and 315/35 rear. Fitting any of these sizes without rubbing shouldn't be an issue, my only concern is I don't want the tires to look too small or too big for the wheels. I'd like to get a size where the sidewalls will end up damn near square to the wheel, or maybe a slight outer bulge. I'm looking at the Toyo Proxes ST II, so if anyone knows about pros/cons of this tire, please let me know. Thanks!

Jeff those are some awesome tires. I have them on my DD 07 VMAX. 285/50/20. I would go 275/40/20 28.7 in tall and 295/40/20 29.3 in tall. The only thing is Toyo recommends a little wider wheel on front than 8.5 maybe 9 or 9.5. Hope this helps.

Thanks! Well I may have to run a narrower front tire as I've already got my wheels, too late to change those... LOL! After looking at their site some more, I think I'll go with 255/40 fronts. I also just found out that Toyo solved their backorder issue on the 295's, so it looks like I'll be calling Driverz Inc in the next week to place my order.
