I have searched but cannot find the answer. I am going to go get some new tires for our '05 SCREW 5.4L 2WD with the oem roush 20's. Currently they have 275/55-20's.

My questions:

1) What is that rim's width?

2) What is the largest tire (both height and width) someone has put on a 2WD non lifted F150? Not too worried about the speedo difference, but only with rubbing issues.

3) Whats most people running brand and model wise for 20's. I do no offroad but pull the boat to the lake 2-3 times a week. It's a pretty big wakeboard boat and can use all the extra traction at the ramp I can use.

Thanks in advance for all the help.

Cheers!
