Rubi owners can now have those bling bling longfields for their 44s. If they are anything like the Toy birfs, they'll take some big abuse.
My toy stuff held up just fine, until I moved to 38.5s, and really beat it(apparently blew the r & p's, although the rear was still driveable, and the front just popped from time to time). So I'm moving back to 37s, and taking 1000lbs out of the rig. No ball joints, great ground clearance and weight, blah...
I do think that with gas, economy, etc, people will be scalling back a bit.
