Anyone got a good source (say on-line) or recommendations on 'big' truck tires. The 1510 just ended up with a flat in the front (appears to have a hole in both the tube and the tire), and the other day I noticed the KB lost a valve stem on the rear and killing a tire (not that they weren't junk already). the KB needs 9.00/20's, and the 1510 needs 7.50/20's front and 8.25/20's rear. I don't have any hook ups at any local tire shops, so I'm shooting blind there (never know if I'm getting a good deal or a hose job, or they don't care since I'm not a corporate client). I had a guy last year that was wanting to work with me for the KB back when I first got it, but never came through, we've lost touch and the contact I meet him through has gone down the road (not that that means too much, but name dropping never hurts I've found). I sourced a set of 19.5 non-splits for the 1510 once (only two rims/tires but the tires were too short to match the 7.50/20;s), but I just went by there and they aren't where they were stored any more. I'll have to see if I still got the guys number. I've even thought of going with 22.5's for the KB. Loose the splits, common tires etc. Maybe get a deal on a complete set mounted and ready to go. What you guy think?
