Note: I know there is a "Wheel & Tire" forum, but it's dominated by people looking for 4x4 wheels and tires, hence I'm posting here in the "Street Truck" forum to hopefully reach the correct audience.
I'm in the market for new wheels now that I finally got my new truck (2013 2wd regular cab) and I'm trying to decide if I want to go with 19" or 20" wheels. Since the 4 cylinder Tacoma is pretty much a gutless wonder in terms of horsepower, I'm trying to strike the right balance between looks and functionality for daily use.
While wheel shopping online, the most recommended tire size is a P255/35/20 which leaves very little sidewall protection. I've found quite a few forum posts about people with this size tire reporting bent rims and wishing they had gone with a 40-series tire.
Many people go with really wide tires which, even with an aspect ratio of 35, gives a decent amount of sidewall protect. However, even though wide tires look cool, they also weigh much more, increase rolling resistance (which means they decrease fuel economy), and they have a tendency to 'drive the vehicle' (I.e., the tires follow ruts in the road). If my truck was a V6 X-Runner, I'd consider wide wheels and tires, but it's not... it's just a slow, underpowered truck.
After doing some research, a P245/40/20 tire almost seems too good to be true. It's a readily available size tire, it's wide but not too wide, and the only disadvantage I see so far is that it's slightly 'taller' than my OEM tires which means my speedo will be off a little. In theory, this tire size has a 3.9" sidewall height which is a tad more than the 18" tires I had on my last truck.
For comparison, here's the stock 15" tire compared to the the P245/40/20:
And here's the stock X-Runner P255/45/18 tire compared to the P245/40/20:
Once again, the P245/40/20 is still pretty beefy, but just a little narrower than the X-Runner tire, which I think is OK since my truck is no X-Runner.
What are your thoughts on a P245/40/20 tire with either an 8.5" or 9" rim? Yeah or ney? If you know of a Tacoma with this wheel size, I'd appreciate some photos of it.
