Tamarock MT
Arroyo Tamarock MT tires: big flotation sizes built for full-size trucks
Arroyo Tamarock MT tires come in tall, wide flotation sizes made for full-size trucks and lifted rigs. Every fitment we stock measures a full 12.5 inches wide and stands either 33 or 35 inches tall, so this is a model aimed squarely at larger builds rather than daily-driver dimensions. Below you'll find the exact sizes, ratings and prices we carry.
The sizes we stock
We carry the Tamarock MT across 17-, 18-, 20- and 22-inch rim diameters, in both 33- and 35-inch outer diameters. Representative sizes include:
- 33X12.5R17 at $275 — the most affordable fitment we carry
- 35X12.5R18 at $349 — a taller 18-inch option
- 33X12.5R20 at $303 — a 20-inch pick
- 35X12.5R22 at $362 — the largest we stock
These are the sizes we actually carry for this model, not the model's complete size range. If you want a ready-to-bolt setup, our mounted packages pair tires and wheels together.
Ratings on file
Every size we stock carries a Q speed rating. Load indexes run from 114 all the way up to 128, with service descriptions spanning 114Q through 128Q. Load ranges are E and F, reflecting the heavy-duty construction expected on 12.5-inch-wide truck sizes.
Price band and who it suits
Pricing runs from $275 to $362 per tire, which lands the Tamarock MT in the value tier for full-size flotation sizes. It suits truck owners who want serious 33- or 35-inch dimensions without paying premium-brand money. If your build calls for smaller car and crossover sizes, siblings like the Eco Pro HT and its updated Eco Pro HT2 cover different needs, while the Grand Sport 2 is a lower-profile street option and the Eco Pro AS targets everyday passenger fitments.
