they are 36's in the first pic, 39.5x15 in the second, same suspension.
the 39's werent mine, just use em every now and then.
as for the 435, i love it. the 6.68 first gear works great with my bw 1356 low range and the 3.55 gears and the 39's. have around a 70to1 crawl ratio, and still runs good on the road.
only thing is, no speed shifting. lol
