Mitas AC85 R-1W Radial Tractor Tire

The Mitas AC85 is a radial tire: a deep-lug drive tire for wet or heavy soil and tractors that log many field hours. We list 7 sizes, from 320/85R24 to 520/85R38.

What are the Mitas AC85 specs?

Load, ply and price for each size are in the size table above. They come from the maker catalogs we sourced and are confirmed again in your quote.

Which sizes does the AC85 come in?

Each size links to its own page with the width, rim and fitment notes. Not sure which one your tractor uses? Read it off the sidewall of the tire you are replacing, or use the tire size converter.

How do you read the AC85 size?

Take 320/85R24 as an example. It is 320 mm (12.6 in) wide on a 24 in (610 mm) rim. The R in a radial size marks the construction, and in a metric size the first number is the width in millimeters and the second is the aspect ratio. Our tractor tire size guide explains every number on the sidewall.

Before you order, check four things: the rim diameter matches your wheel, the load rating covers your heaviest working weight, the new tire matches the other tire on the same axle, and the size matches what the tractor maker approves.

What the AC85 is built for

The Mitas AC85 is sold as an all-season tractor tire with an aggressive lug pattern for soft, loose and uneven ground. The maker describes a wear-resistant compound with even tread contact, a reinforced internal structure and quicker steering response.

Mitas does not list a tread code on the pages we read, so we do not assign one here. If you run it on loader or front-axle duty, compare the load rating in the size table with your actual axle load before you order, and send us your size on WhatsApp if you want a second pair of eyes.

Who does the AC85 suit?

Choose it if your ground stays wet or heavy, or the tractor logs many hours a year. R-1W lugs run about 20% deeper than R-1, so there is more rubber to wear and more bar to bite with. The rim range, 24 to 38 inches, covers utility through row-crop tractors.

What are the limits of the AC85?

R-1W costs more than R-1 and the deeper lug adds weight and road noise. For dry ground and light yearly hours a standard R-1 may be enough. The R1 vs R1W guide helps you decide. Radials also need careful pressure setting: use the maker load table for your weight.

How does the AC85 compare with similar tires?

These models in our catalog overlap with the AC85 in size, so they are the ones you are most likely to be choosing between. Compare price per tire in the size tables, and compare the tread and load data, not only the brand name.
