Maximum tire size for reg cab 2nd gen

Hello every one. I posted this on the 2nd gen section but it seems more appropriate here.
I had 265/75/16 BFG KO's and it had no problems. Now with the Toyo Open Country it seems more jerky when shifting from 1st and 2nd. Unfortunately I also got E load rated. From what I read I should have gotten 265/70/16's

Im worried about toasting my clutch. Any advice much appreciated.

 

So they are 116 load rated actually and I dont know the letter.

 

You should be able to run 265/75/16 no problems. Swapping to new tires shouldn't cause a truck to be more jerky. This might sounds dumb, but make sure all 4 tires are all the same size.

 

I had walmart put tires on my odyssey once and they put one of the tires on in the wrong size. I think the shifting is just they way they are.
Not sure but the Toyo's seem to make some road noise, not the tires, too true. Idiot before me put in 3 inch spacers.
844's and billies on the way. Im not sure what the 20mm of the /265/ gets you.
