Tires: Substituting Tire Sizes, 2008 toyota highlander, toyota highlander

Question
My 2008 Toyota Highlander Sport wears P245/55R19 tires, which have proven difficult to locate. Is there a substitute size compatible with my wheels (e.g., I have found P255/55R19 tires available locally).

Thanks!

Answer
Mitch,

255/50R19

265/50R19

Here's a calculator to see how far off your odometer would be:

BTW, the 225/55R19's are smaller in load carrying capacity and increase the risk of a load related tire failure, which sometimes has tragic results.
