My '08 Harley F-150 came with 275/45/22.
If I level, will I be able to fit 70's with no issues on the front clearance?
The back looks like they should do fine but not sure if turning will be an issue with fronts.

 

Kinda strange i was just about to post a similar question. What size level are you going to go with?

 

Not sure. Just enough that front tire has clearance. Maybe 3" or so.

 

That's over 37 inches. It probably won't fit. I think the largest you can possibly get away with is 35's

 

Thanks. That answers another question that I've had for some time.
After what size does the count change to 33's, 35's. I've heard those #'s and saw that they were larger tires but didn't know where it came from.
Thanks alot.

 

its just two different measurements of the tire. the metric numbers give tread width and sidewall height, but not total height, whereas the inch size gives you total height of tire total width and rim size(so a 33x12.5r15 is the same as a 33x12.5r20). The 33 adn 35 numbers are kind of old school but still relevant when comparing tires. If you search for a tire converter tool on google and put your tire size in there, it will tell you the equvalent tire size in inches.
