Frequently asked questions
Quick answers about UK tyre fitment, MOT rules and seasonal options.
How often should I rotate tyres on a MG MGB?
Most tyre makers and MG workshops recommend rotating front and rear every 5,000-7,500 miles for even wear. Front-wheel-drive cars typically wear front tyres faster; rotation extends overall tyre life.
Can I mix tyre brands on a MG MGB?
It's safer to fit matching tyres in pairs (axle-by-axle) on a MG MGB. Mixing brands or different tread patterns across an axle can affect handling balance — particularly in wet conditions.
Is wheel alignment important after fitting new MGB tyres?
Yes — a wheel alignment check after fitting new tyres on the MG MGB preserves tread life and handling. Most UK fitters offer a quick alignment check; major adjustments (camber/caster) require a four-wheel laser machine.
Where can I find the tyre size for a MG MGB?
On a MG MGB, the original tyre size is shown in three places: the existing tyre sidewall, the placard on the driver's door frame, and the vehicle handbook. The door placard is the manufacturer-specified original equipment.
How do I find the right tyres for a MG MGB?
Start with the size printed on your existing tyre sidewall — for example 205/55 R16 91V — and use it as your baseline for the MG MGB. Match width, profile, rim size, load index and speed rating before considering brand or pattern.
