Hello, I am looking to upgrade my 17" wheels on my 2010 Ram 1500 Crew Cab 4x4. I would like to go with a 20" rim and a larger truck type tire. My question is how big of a tire can I go with without causeing rub. Also how will this effect my speedometer?
I am currently looking at the the following, is this the correct lug?Brand: KMC XD-SERIESModel: 797 SPYSize: 20x9 Finish: Chrome PlatedOffset: HPO/STD/REV/MEDLugs: 5 x 139.7

As far as tires go i was looking at the following:
Brand: NITTOModel: Terra GrapplerSize: 285/50/20Speed Rating: STreadwear: 500

Any other suggestions would be great even open to rim and tire type. Anyone upgrade there's yet would love to see some pics.

Thanks, Andrew
