Thanks guys! I'm curious if anyone has custom ordered anything larger than 12.4R24 fronts on a 5M without running into issues.I should know what tire size they are since I just got my 6430p last year.... I will check the quote I have and see what size they are....
I understand that you want the front axle speed to be between 1-5% faster than the rear. So the challenge would be to find something wider for the front, and get something that would match on the rear while maintaining the 1-5% faster ratio.
Perhaps a conservative step up would be a 14.9R24 on the front, but I'm pretty sure I would have to up the rears as well to maintain a proper axle speed ratio.
Here are some numbers using Titan Hi Traction Lug specs:
I don't know the front/rear drive train ratio of the 5085M, nor do I know if a 18.4R34 will clear the rear fenders.
I suppose the perfect solution would be if JD offered some wide R24 rims with a tire that was close to matching the 138" rolling circumference of the stock 12.4R24. This way, I could leave the rear tires/rims alone.
