I have a 2004 Toyota Tacoma Prerunner. I think my current tires are 16", but a friend is offering to sell me brand new 17" tires for a real reasonable price.
Yeah-but there is a downside.
If you go with those low profile tires you will lose ride quality. You will start to feel every single bump. It causes a harder ride on the suspension, causing the suspension parts to wear out much quicker.
I had 17s on my car, it looked great but the ride was terrible. I went through 2 sets of shocks within 3 years, my mechanic said that those thin tires and oversized wheels can cause your suspension parts to wear out faster. I went back to the stock 15s and it rides great.
