Good day all, I have a trip planned for Alaska in two years and I have already been looking for nice tires. I have an 82 r65ls and I am looking for more of an "adventure" type tire. It is kind of hard finding ones that match the tires I have on there now (110/90 x 18 rear and 100/90 x 18 front) I have found these tires, Kenda k761 dual sports but the only size close enough is a 110/80 x 18. I understand the aspect ratio but do you think it would make much of a difference having an 80 verses a 90? I guess I am really wondering if these tires would work on my LS? And if anyone has tried them here. Thank you for your help and have a great day.
