Getting ready for new shoes on my '05 Lariat Scab and thinking of going from the stock 265/60/18 to a 275/60/18. The latter is only slightly larger and I know it will throw my speedo off about 1 mph, but I'm wondering if maybe I could have a problem with any rubbing on the fender or wheel wells in excessive turning situations. Anybody got any thoughts/ideas? My goal is to fill up the wells a little more than they are now. Thanks

 

I am assuming this is a 2 wheel drive? The tires you have now are ~30.5''x10.4'', the new tires will be ~31''x10.8''. So you are not looking at a much of a difference here. I think you will be just fine.

 

They will fit easily.
