One thing I found out to watch for is the load rating on the tires. Some manufacturers label them as “ATV/UTV” tires but the load ratings are really only good for ATVs. I ordered a nice looking set of 6 ply tires for my 700-4 but couldn’t find the load rating on them, decided they would probably be ok. Well when they showed up I saw right on the sidewall that each tire was only rated for 440 lbs (52 rating). No way is that good enough for a UTV and I absolutely would NOT run them on my side by side with 4 people. Would be very unsafe. So back to the dealer they went.
Reordered some Kenda Bear Claw HTR 8 ply tires with a 116 load rating which means each tire is good for 2756 lbs. WAY more than I’ll ever need but don’t have to worry about total weight on my tires even with a big load in the bed.
