Here is a summary of what I've discussed in other posts.
I've decided to go with General Grabber A/T2s for the following reasons:
1. Decently rated A/T tire.
2. Has the snowflake, which makes it eligible for the 'winter tire' program through my car insurance company.
3. The P version of the tire comes with a 96000km treadwear warranty. LT does not, but I assume (perhaps incorrectly) that the treadwear would be similar if I kept the load/pressure the same.
Now I need to decide whether to go with P265/70/16 or LT265/75/16. The difference is the load rating, primarily. Keep in mind that I do occasionally tow a travel trailer, it has 400-500lb tongue weight, approximately 5000lb overall weight.
The load ratings for the tires are as follows:
P265/70/16 - SL Rated - 2469lbs x 2 tires = 4938lbs
LT265/75/16 - E Rated - 3415lbs x 2 tires = 6830lbs
The numbers I've been able to dig up is that our rear axle is rated for a maximum of 4200lbs. Therefore, it would not make sense to go with the LT tire, as the P rated tire exceeds that maximum load value by a fair margin. They would be way overkill.
Does my math make sense? Does anyone have better info on the rear axle max load capacity?
