What Is The Ideal Rim Width for LT275 65R20 Tires?

The recommended rim width range for LT275/65R20 tires is 7.5 to 9.5 inches. Most LT275/65R20 tires have a 10-ply construction (Load Range E), though some are available in lighter load ranges. The width of the rim you choose will have a big effect on how the tire performs and how it contacts the road:

• 7.5" Rim (Minimum): This is the usual width for many factory heavy-duty wheels, such as those on older Ford F-250s or Ram 2500s. It offers the most protection for the rim against curbs and debris because the sidewall sticks out a bit past the wheel.
• 8.0" – 8.5" Rim (Ideal): This size lets the heavy-duty tread sit flat on the road. It is the best option for even tread wear, especially if you often carry heavy loads or tow.
• 9.5" Rim (Maximum): This size stretches the sidewall. It can make steering feel more responsive, but it also makes the ride stiffer. With an LT tire at high pressure (up to 80 PSI), a 9.5" rim can feel very harsh over bumps.
