Understanding the 235/50R17 size

In the size code 235/50R17, 235 is the section width in millimetres (about 9.3"). 50 is the aspect ratio — the sidewall height is 50% of the width, or roughly 117.5 mm. R17 means radial construction on a 17-inch wheel, giving an approximate overall diameter of 26.3".

The load index 96 means each tire supports up to 1,565 lbs — about 6,260 lbs across a full set of four. The speed symbol V certifies the tire to 149 mph under its rated load. Always match or exceed the load index and speed rating listed on your vehicle's door-jamb placard.

What the Bridgestone Ultraweather is built for

The Bridgestone Ultraweather is a winter tire, using a cold-weather compound that stays pliable below 45°F (7°C) where all-season rubber hardens and loses grip. It carries the three-peak mountain snowflake (3PMSF) symbol, meaning it passed a standardised severe-snow traction test. It is classified for highway terrain(h/t) use.

Tread life and grip ratings

This tire carries a UTQG rating of 600 A A. The treadwear grade of 600 is a relative durability score — a grade of 200 is expected to last roughly twice as long as a grade of 100 under the same controlled test. Traction grade A measures straight-line wet stopping grip (AA is highest, then A, B and C). Temperature grade A reflects heat resistance at sustained speed (A is highest).

Price and value

At $160.49 per tire, a full set of four costs $641.96. That is about 20% above the average of the 61 tires we stock in this size, reflecting its position in the range. Backed by a 60,000-mile treadwear warranty, that works out to roughly $10.70 per 1,000 miles across the set.
