Why the rear tyre matters

The rear tyre supports traction, stance and stability. A 275/30R20 rear tyre is wide and low-profile, so it must be matched carefully with the rear wheel width, offset and suspension clearance.

What to check on the rear axle

Important rear checks include:

• inner clearance to suspension
• outer guard clearance
• wheel offset
• tyre shoulder profile
• load rating
• pressure setting
• rear toe and camber

Alignment and wear

Rear toe can wear a wide performance tyre quickly if it is out of specification. Because the rear tyre is different from the front tyre, front-to-rear rotation is usually not available. Alignment and pressure maintenance become more important.
