The Thunderer TRAC GRIP MT R408 tires are a large-diameter, high-load option built around wide, tall casings that suit trucks and SUVs running serious weight. Everything below reflects the sizes and ratings we actually stock for this model, so you can see exactly what is available and what each fitment is rated to handle.
The sizes we carry
We stock the R408 in 16-, 17- and 18-inch rim diameters. Representative fitments include the 315/75R16, the 315/70R17, the tall 305/70R18, and a narrower 235/80R17. These are the sizes we carry, not the model's full size range. If you already run one of these, the wider 315/70R17 and the 235/80R17 category pages show other options in those dimensions too.
Ratings on the sizes we stock
Every R408 fitment we carry uses the Q speed rating. Load indexes run from 120 through 121 to 126, giving these tires plenty of load capacity for full-size trucks carrying gear or towing weight. Those service descriptions read 120Q, 121Q and 126Q depending on the size.
Price and who it suits
Pricing on the R408 runs from about $278 for the 235/80R17 up to roughly $391 for the 305/70R18, with the 315-series sizes falling in between. That is honest mid-band pricing for a big, high-load tire — a sensible pick for owners who want capable rubber without stretching to premium money.
Shopping the wider Thunderer range? The R408 TRAC GRIP 2 is the closest sibling and worth a look, while the UA411 and MACH V lean toward on-road driving, and the Commercial CLT targets heavier commercial duty. You can browse the full lineup on the Thunderer hub or across all tires.
Ordering
Every order ships with free shipping on all orders. Financing is available at checkout, and if you'd like a hand confirming a size, call us at 813-535-5801.
