Critical Rubbing Points & How to Fix Them

Specific areas where oversized tires rub on the Ram 1500 (Classic & New Body Style) and proven solutions.

1

Upper Control Arm (UCA) Ball Joint Clearance

Factory stamped-steel front UCAs sit exceptionally close to the inner tire sidewall. Tires wider than 11.5 inches (such as 35x12.50 or 295mm) will make direct contact with the UCA ball joint cup on stock wheels.

The Solution: Run 1/4" wheel spacers, aftermarket wheels with 0mm to +12mm offset, or upgraded aftermarket tubular UCAs.
2

Front Lower Air Dam & Inner Plastic Liner

Tires exceeding 33.5 inches will brush the front lower plastic valence and the inner rear wheel liner during full steering lock in reverse.

The Solution: Trim 0.5" off the lower plastic front air dam corner and heat gun/zip-tie the rear plastic fender liner back against the cab.
3

Factory Air Suspension (Rebel / Limited Models)

Models equipped with factory Active-Level Four-Corner Air Suspension sit 1" lower in Aero mode at highway speeds, which causes previously clearing tires to rub if fitment was too tight in Normal mode.

The Solution: Install aftermarket air suspension sensor links (adjustable leveling links) or stick to max 33.5" tires.

Wheel Offset & Backspacing Advice

Why offset matters as much as tire diameter.

The sweet spot for a leveled Ram 1500 is a 20x9 wheel with +12mm to +18mm offset. This gives a subtle aggressive stance, pushes the tire away from the fragile factory UCA ball joint, and avoids hacking your fender liners.

Frequently Asked Questions: Ram 1500 (Classic & New Body Style) Tire Fitment

Can you fit 33-inch tires on a stock Ram 1500 without a lift?โ–ผ

Yes, 33-inch tires (such as 275/60R20 or 275/70R18) fit easily on a factory stock Ram 1500 with zero rubbing and zero suspension modifications. Rebel trims come from the factory on 33-inch Goodyear Duratrac tires.

Will 35x12.50 tires rub on a leveled Ram 1500?โ–ผ

Yes, 35x12.50 tires on factory stock wheels WILL rub the front upper control arm (UCA) ball joint cup because the tire is too wide. To run 35s cleanly on a 2-inch leveling kit, either choose a slightly narrower tire (35x11.50 or 285/65R20) or install aftermarket wheels with +12mm to 0mm offset.

Do Ram 1500 trucks with air suspension have different tire clearance?โ–ผ

Yes. Ram 1500 models with factory 4-corner air suspension lower by roughly 0.6 inches into 'Aero Mode' at speeds above 65 mph. If your tire clearance is razor-thin in 'Normal Mode', you will experience highway rubbing unless you use aftermarket air link sensor levelers.
