Tire clearance depends on four things: lift height, wheel offset, tire width, and the truck's own fender and frame shape. Because the first three are all your choices, the only honest number is the one the suspension manufacturer publishes for a specific kit at a specific setting. That number is on every lift, leveling and coilover product page on this site under Max Tire, copied from the brand's own fitment data. We do not estimate clearance and we do not quote forum results.
Rules of thumb that hold on most full-size trucks
- Stock height: 32 to 33 in on a factory-offset wheel.
- 2 in level: 33 in on most half-tons. 34 in on some with a wheel that pushes the tire out, at the cost of rubbing the liner at full lock.
- 2.5 to 3 in coilover lift: 34 to 35 in, usually with crash-bar or liner trimming for a true 35.
- 4 in: 35 in clean.
- 6 in: 37 in.
What changes the answer
- Offset. A negative-offset wheel moves the tire outboard, which clears the UCA and frame but hits the fender and liner sooner. Zero or slightly positive offset keeps it under the fender and uses the suspension clearance.
- Width. A 33x10.5 clears where a 33x12.5 rubs.
- Trim. Raptor, Trail Boss, Rebel, TRD Pro and similar have their own fender and frame geometry. Their numbers are different and our listings exclude them unless stated.
When in doubt, email the truck, wheel size and offset, and the tire you want to support@hannahsuspension.com and we will check the manufacturer data before you buy.
