About this guide
Tires and Wheels in Phoenix is an independent written reference for people who drive in the Valley and want the sizing, fitment, and heat basics in one place.
What this site is
The pages here explain how to read a tire sidewall, how a wheel sits on a hub, how desert heat ages rubber, and how to compare two metric sizes. They are written in English for drivers in and around Phoenix, where summer pavement, monsoon rain, and a lot of trucks share the same roads. The site does not sell tires or wheels, does not book installations, and does not list shops.
It is also not a fitment catalog. Nothing here confirms that a named wheel clears a named brake package. Examples such as 265/70R17 are illustrations of the arithmetic, not a recommendation for your vehicle. The door placard and a physical check outrank every example.
What this site is not affiliated with
This guide is not a subsidiary page of a tire retailer, a manufacturer, or a dealership. It does not carry their offers, and it does not send you to them. Product categories are described in general terms so you can talk precisely with whoever does the work. Names of freeways and seasons are local context, not endorsements.
If you use the upsize calculator, treat the result as geometry. The terms state the limits of that estimate. The privacy page explains that the site does not ask for an account or run advertising trackers.
Questions
Can you tell me which tire fits my truck?
No. Use the guides to understand the numbers, then confirm fitment, load, and pressure for your exact vehicle with the placard and a qualified installer.
Is the upsize calculator a fitment approval?
No. It only compares overall diameter, sidewall height, revolutions per mile, and the speedometer difference that follows. A result inside 3 percent can still rub if the wheel width or offset changed. Read the plus-sizing guide next to the number, and measure clearance on the vehicle.
