Rusker Posted July 17, 2018 Share Posted July 17, 2018 I'm in the process of getting our 1977 chinook ready for a 3 week roadtrip this September. One thing I'm planning to do is to get a fresh set of tires. I'm looking at (4) Yokohama 356 "super vans" in 195/75r14, but I'd like to get something a little more aggressive for the rear. We plan to do a lot of traveling on forest roads, dirt roads, and general areas where cell reception will be limited at best. I'm concerned the 356 tread pattern is more suited for pavement only. I know this topic has been discussed multiple times. Some believe load range D is the only way to go and some believe load range C is acceptable. Unfortunately the option for an AT rear tire are very limited and load range D is not an option. Here is one option I was considering: General Grabber AT2 (load range C) 27 x 8.50 r14 max load - 1520lbs 50 psi For comparison: Yokohama 356 (load range D) 195/75 r14 max load - 1710lbs 65psi Has anyone used this tire, or know of a better option? If this would work would you guys recommend AT in the rear only, or replace all 4 (+spare) to avoid issues with mismatched tires if the spare is needed. Thanks in advance!

linda s Posted July 17, 2018 Share Posted July 17, 2018 Load range D is for heavy vehicles. Have you weighed your Chinook? The General Grabber is more than enough tire and I bet you could manage with an XL tire just fine. That would give you wider range of choices. Chinooks originally came with a wider tire in the back for stability. Easier to have them match though for flats. Linda S Quote Link to comment Share on other sites More sharing options...
Rusker Posted July 17, 2018 Author Share Posted July 17, 2018 (edited) I haven't but I'll take a look at the tag on the door when I get home. It's 4,500lbs +/- An XL meaning? If the 27x8.50 r14 ATs work I'd like to put them on all four corners (including the spare) even though it's only a 2wd. Just one less thing to worry about if I get a flat.

Derek up North Posted July 17, 2018 Share Posted July 17, 2018 I think 'XL' is for 'Extra Load' and are rated at 44psi (from memory). I think the only concern would be with the AT tires possibly rubbing on something when up front. They might also be too wide to install on standard rims.

Gotcha One reason I'm considering this is because I bought a parts truck, and it had a set of old ATs on the rear. The wheel appears to be the same size as my own chinook wheels and the tire was a 27x8.50r14. My chinook is currently on jackstands, but when I mounted the AT on the front I can turn it lock to lock and it doesn't appear to hit anything. I'll do the same once it's on the ground and see if I get the same result. Quote Link to comment Share on other sites More sharing options...

linda s Posted July 20, 2018 Share Posted July 20, 2018 Seems heavy for a Chinook. So the XL tires won't cut it. If the Generals fit they'll work Linda S Quote Link to comment Share on other sites More sharing options...
