On a stock (no lift) 98 2500 Quad Cab 4x4, what is max tire size it can take. Also, does anyone know the max tire size the std 6.5x16 wheels can take?

 

I would put a 305/70/16 on there. That basicly equals a 33x12.50R16.

 

Alot of places won't mount the 305's (~12&quot; wide) on the 6.5&quot; wide rims. If you want approx the same height you can run 255/85's which are only 10mm (~0.4&quot wider than 245's AND can be safely mounted on the 6.5&quot; rims. Only drawback to the 255's is their 'taller' sidewall relative to width. Has about the same sidewall height at ~8.5&quot; as the 305's but on a narrower tire. Not an issue as far as I'm concerned but you &amp; others may feel differently. All widths are nominal &amp; cross-sectional NOT actual contact patch which is narrower.<br><br>Good luck

 

Oh i didnt know that you were mounting them on 6.5 rim.

 

Am still debating whether to go to a new wheel so as to get a larger tire, or stay with stock wheel and go with smaller tire. I was told you can mount 285x75 on stock wheel??? Will the 305's clear ok with stock suspension?

 

yes they will, I have them on my stock rims right now.-{but not for long!!} ;D ;D ;D

Someone mentioned a 6.5&quot;--that's the earlier truck. Later trucks have 7&quot; wide wheels. Sorry, but I'm not sure where the split is year-wise. You might be able to find that info on http://www.dodgeram.org. He's got quite a bit of stuff on there. As far as recommended rim widths for various tires, the best source is the tire manufacturer. I know Dunlop posts that on their website. I had a 98 1500 with the 7&quot; rims on it that had 285/75-16s on it when I bought it, so it should work ok.
