I'm waiting on delivery of my 2010 F150 AWD Harley Davidson edition and was looking to replace the Pirellis with a tire that can run through the Canadian winters. I was originally looking the the Cooper Zeon LTZ until I realized that it came only in a 305-40-22....and I'm concerned about having a bit more sidewall. I know the 305-40-22 will fit with no lifts or levelling and I'll have no rubbing issues. Does anyone know if the 305-45-22 cause me any problems with rubbing?

 

It's literally gonna be a half inch to an inch wider than the 40 and the 2010 models sit high enough that you wont have to worry about it. Especially the AWD

 

OK thanks. I've seen people mentioning on the various forums about running into issues with rubbing on the upper control arm even with the 305-40-22, that's why I ask.

 

that is wrong, sorry if that offends you but the aspect ratio (the second number) has nothing to do with the width of the tire

305/40/22
12" wide
4.8" tall sidewall
31.6" overall height

305/45/22
12" wide
5.4" tall sidewall
32.8" overall height

so you are basically running a 33" tall tire since not all tires even though they are the same size they may actually be a little off. now that means your tire will only be a hair over half an inch closer to the fender

 

So then I should be OK with the 305-45-22?

 

I just read on another posting that someone mentioned that the 305s call for a wider wheel than the stock wheel (which I believe is 8.5") and they would wear down the middle quickly if the rims width is smaller than what the tire size calls for.



So if I put on either the 305-45-22 or 305-40-22 am I going to be looking at prematurely wearing out some expensive tires?

 

I have 305-40-22 on my 07 Harely with stock 22s






Granted yours is a 2010 rim size may be different. I have a little over 1500 miles on them and they haven't shown any irregular wear. I drove from MS to Washington D.C. to NC a week after putting them on. I love them!!! Nitto 420S 305/40/22

 

Well I finally bit the bullet and bought the Cooper Zeon LTZ 305-40-22s for my Harley. No rubbing at all. Thanks everyone for the information.

 

very nice!

 

Beautiful truck! Tires look good and aggressive.

 

Thanks for the compliments everyone.

 

yeah that is so sexy.

 

I run the Toyo proxes STII's in a 305/45/22's on 08 H.D. rims , no rubbing . I also have a 2/4 drop. 4wd

 

Can you post pictures of your truck?

 

I'd like to see those pics too..
