Question:
Yes, I currently have 4.80-12 tires on my trailer 6x10. I would like to put on as big as possible bigger/wider tires, but not sure which size to purchase. From center point up to the fender is 14 1/2” and fore and aft of center point is 11 1/2”. Thanks

Hey Brett, thanks for reaching out!
The largest tire that will fit your application is a 145/85-12 and it will be about 1" larger diameter than your current tire. I recommend going with the Kenda Karrier S-Trail which comes mounted on wheels with the following bolt patterns:
- 4 on 4" # AM35351DX
- 5 on 4-1/2" # AM31199DX

Hey Brett, how did the 145/85-12 tires work out on your 6x10 trailer? Did the extra inch of diameter give you the clearance and look you were hoping for? Your update could make it easier for the next person wanting to size up their trailer tires.
