Questions about this item

What rim diameter must I already have for the 225/40R18 92W XL tire to fit?

The tire is built for an 18‑inch rim, so your wheels must be 18 inches in diameter.

Will the 420 treadwear rating and 7/32 tread depth match the grip of my older all‑season tyres?

The 420 UTQG treadwear grade and 7/32 starting depth give a firm baseline; expect similar or slightly longer wear than many older touring tyres.

How can I confirm the 92 load index and W speed rating are performing correctly after installation?

Check that the sidewall shows 92W, verify cold pressure matches the vehicle placard, and monitor even tread wear across the 225 mm section width.
