I ran TSL 38" swampers for 3 months last year. I got them at a tire place that had free balancing & I would have to have them balanced about every 500 mi or they would start "shaking" the truck at high speed.
I sold them & converted to MTR's. IMHO, the MTR's are superior for off-road traction here in Colorado & they run at 85mph like a cadillac compared to the TSL's. Just my $0.02 Now there's no other tire I would run on my Hummer other than my current 37" MTR's (except maybe 40" mtr's
)
