rogerholland98@hotmail.com Posted May 27, 2023 (edited) I have a 2013 NV1500, which calls for LT245/70R17 tires. Can I run LT245/75R17 (75 vs 70), without a serious problem? Has anyone ever done this? Edited May 27, 2023 by rogerholland98@hotmail.com Quote Share this post Link to post Share on other sites
Local Apparent Friday Posted May 30, 2023 The 75's appear to be OE on the 17+, so you should be fine since the chassis is the same. I went up to 285, but can't remember if i'm 70 or 75. Van is down now with the trans pulled out, but when I'm there again I'll look at the tire size and check. 1 radin2son reacted to this Quote Share this post Link to post Share on other sites
crusty Posted May 31, 2023 245/70 to 245/75 will be changing to the 1-ton tire size. The speedometer will be more accurate with them. shouldn't notice anything else. Quote Share this post Link to post Share on other sites
