Tire selection and sizing help
I am looking for upgrade the tires on my van. The van came equipped with 17x8.5 wheels and 285/70/17 Hankook Dynapro atm tires. Front tires are fine, but the rears a getting a little low; I could just buy two new rears, but I'd like t upgrade to "E" rated tires and the Dynapro is a "D" rated tire.
I've read a many postings here and based on my research, the BFG All Terrain T/A KO appears the best choice -- like many 4x4 owners, I drive the highway 90% getting to my off road destination, so I want something decent on the highway. Off road usage is modest, I am not into hardcore wheelin', just want to get through mud, snow, sand when necessary. Are there other tires I should consider?
Then to the topic of size: in "E" load rated BFG offers the T/A in two sizes that fit my wheels: 285/70/17 and 305/65/17. I would be inclined to choose the wider tire due to increased foot print, but wonder about the lower profile sidewall at "only" 65. Thoughts on this? I've also looked into 33's or 35's but I am new to truck tires and I am not clear what would fit my wheels.
Appreciate the help.
