:rofl: Those are my "Itty Bitty's", they hold their own. The lift makes them look pretty goofy. FYI-acording to John @ M&H, the new 275-55-16 DR's have 1/2" more roll out, are a little wider and softer. They are still listed with the old measurements though. Mine measure @ 27.5" tall...
The biggest you can get for our stock PYO's in a DR, 275-55-16. I spoke to M&H about larger sizes, but the tooling would be $60K. The next step is a 9"-10" rim, but these have absolutly no problem hooking.
