Bring the specification, not just the tire size
Your vehicle’s tire placard and owner’s manual are the starting point. Note the specified size, load and speed requirements, recommended pressure, and any different front and rear fitments. A tire already installed on the vehicle is useful context but is not proof that the fitment is correct. Tell the seller about modified wheels or suspension.
Do not substitute the maximum pressure molded on a tire’s sidewall for the vehicle’s recommended cold pressure. NHTSA advises checking tire pressure monthly with a gauge. Follow the vehicle guidance; a monitoring-system warning is not a substitute for routine checks.
Separate condition from product choice
Ask a tire professional to evaluate damage, tread, uneven wear and age. NHTSA identifies 2/32 inch as the point at which tires are unsafe and should be replaced. That is not a promise that every tire above that depth is suitable for every condition. Tire age and damage matter too. Use the manufacturer’s replacement guidance and ask how the tire’s production date was checked.
If you are replacing fewer than a full set, ask how the choice affects matching, handling and the vehicle’s drivetrain requirements. Do not assume an all-wheel-drive vehicle accepts any mix of tread depths. For a leaking tire, ask whether repair is appropriate after inspection rather than deciding from the outside appearance.

Compare the installed total
Record the exact tire model and quantity, then add installation, balancing, valve or pressure-sensor service, disposal, taxes and any optional protection. Ask which benefits require returning to that retailer, whether a warranty is prorated, and what maintenance records it requires. A long treadwear warranty is one part of a product comparison; it is not a measurement of stopping performance in your conditions.
When buying tires online, confirm the installer’s acceptance, fitting price and appointment before arranging delivery. Check the merchant’s fitment and return rules. Roadworthy currently provides ordinary source links and facility contacts; an affiliate relationship, when active, will be disclosed beside the relevant recommendation.
After fitting
Keep the invoice and tire details. Ask about the manufacturer’s rotation schedule, pressure checks and any follow-up required by the installer. Uneven wear may warrant further inspection; alignment and balancing are different services. Use our alignment guide to prepare that conversation.
