My Irocks were bias they barely ever flat spotted the truck might have gotten 800 miles a year. Sat on concrete and always road driven. I'd go with Irocks over anything else. Ridden in trucks with tsl s, rough man. Maybe I didn't notice it in my truck but I thought the Irocks rode and drove down the road great look good and I would take them over anything else for that size tire

My 38.5x16" Bias TSL's barely ever flat spot and when they do, it's not very noticeable. Takes maybe a mile or two or get them rounded out.

A buddy of mine just happened to have a set of 39.5 IROKs. He took two off his vehicle and brought them into the body shop for me to put on the front to check for rubbing. Had good clearance. Nothing rubbed while just sitting. Probably would if a curb was run over or something. In my own humble opinion I thought they looked just a little to big so I am going with something smaller. Lots of guys like the full fender well look but I like a little more distance. I called super swamper on Monday and the tires I want are on back order for 6 weeks.................................

Like I said, at least IMO the 38.5s are the perfect size. And for the back order stuff, when you get in to this size of a tire dealers don't typically stock them. Summit wasn't even selling them at the time that I bought them! I had to have them reactivate that size so I could buy a set. It took about a week for them to come in. If you go with a tire of this size range, expect to wait for them.

I called super swamper on Monday. 5-6 week back order on the 16/38.5x16.5's. 4 wheel parts said around middle March. Super swamper said to check 4 wheel parts or national tire. 4 wheel parts on eBay is the way to go. Free shipping!! Summit is about $20 more per tire plus a pretty hefty shipping fee.
