Tire Sizes the same?
Right now I have P235/75/R15 tires on my truck now, my friend has some tires that are 30x9.50r15. How close are they in size? Will it throw off my spedo alot? Please dont laugh cause I dont know anything about tire sizes.Matt

The 30x9.5x15 are about 1.12"'s bigger than your current tires resulting in about a 2.5mph diffrence in your speedo. So if your doing 60 your speedo is only reading 57.5. Hope this helps

Are you getting new rims with the tires or are you just using the same? Either way they will fit.

One thing most do not consider is that bigger tires require more power at all speeds, present a larger profile to the wind at speed. They cost you in lost fuel mileage and more wear and tear on suspension parts but yes they do look cool!!Happy 2 Wheeler!
