I have a L2550 4wd that I bought used about a year ago and it came with turf tires. I am looking at upgrading to ag tires for better traction. I've been stuck multiple times (some my own fault) and really need to have better capabilities in the mud. We have a horse farm and put out round bales when ever there's not enough grass (which is about 7-8 months of the year). Plus the turf tires are getting very worn and cracked. The current tire sizes are 13.6x16 on the front and 25x8.5x14 for the rear. I've done some researching and have found out there's a lot more to it than just replacing the tires. Or is it? I think I may need to have new wheels (rear only maybe). From finding a L2550 spec sheet online, it appears original ag tire sizes for this model are 7x16 front and 11.2x24 rear. That where I got the thinking I may need new wheels on the rear. Honestly, the front tires still have good tread, so I could stay with them. What factors do I need to consider on this? Wheels and tires for the rear? With spring coming on, the mud is only going to get worse, so I'd like to make a decision soon. Please help a novice out. I did see the other thread about changing rear tire size, and that got me worried.
