At 51 pounds if you are running the stock wheels you wI'll be around 65-66lbs wheel and tire combo. And substantially taller. I would say yes you will most likely need clutching and if it was me invest in some gear reduction to help the clutching and power loss. As well as some axle upgrades. 65-70 pounds of rotational mass is now into truck territory and requires some pretty heavy parts to hold up. 35s will definitely find your weak links quickly.
OK, changing mind and going with the 33", they weight less than half a pound more and are 33.8 tall and 10.7 wide. won't have to worry (as much). They don't come in till end of February and will be ordering Monday.
50-60lbs per corner is a very common weight for a 32" wheel tire setup. Now add 5-10 pounds to that with a 35 and add 3 more inches of height to the equation and you have a recipe for broke parts. I used to run 35s on most of my 80s toyotas back in the day and i could break parts at any point if I wanted. And those had twice the size of parts as a rzr. And that's with a 4 cylinder that makes the same hp as a 1000xp. I do c that companies are now making 35" tires but I just don't c how these machines will handle it. Sure if you want to cruze around Moab or something they may work. But put them in the east coast and it's going bust things quickly. Everything is way way too small for a tire that size. Unless you do gear reduction, clutch kit, and axles I wouldn't run 35s. 32s will get you anywhere so I just don't c the need and the headache. But hey it's your money. Give it a shot and let us know how it works
Was watching utv qualifying for Koh today and in the 30 mins I watch it 2 cars on 35s broke front diffs. Now these are fully build 50-80000 dollar rzrs and canams with the best parts money can buy. Just goes to show if you push one of these rigs on 35s it's going to bust stuff left and right. I would check out the 32" maxxis roxxzilla. Absolutely awesome tire in the rocks and hard pack. It's what I have ran on a few rigs the past year or so. I ride mainly Tennessee and west Virginia so our terrain is a little different. But I c a bunch of cars at Koh this year running the roxxzilla as well. If u are stuck on 33s go for it. Just really keep the weight of everything you put on your car in mind because in some way shape or form it will have a direct effect on something. Rotational and unsprung weight is a very over looked component and has drastic effects on suspension, steering and drivetrain.
One of the problems is gearing, the 17s we're the last year of decent gearing. On 18+ models low gear was raised about 30%. As mentioned by DBR, rotational mass and unsprung weight because a huge issue with larger tires. When you get to a 35" tires stuff gets real, real fast. At that point basically everything needs to be upgraded to HD parts to handle the additional stress. Suspension components, steering, frame bracing, drivetrain, ball joints, shocks, etc...the list gets long and expensive. It can be done but understand you just don't slap on big tires and expect not to break stuff.
I’m putting the BFG “10 car tire” on a vision beadlock wheel. I will weigh them and let everyone know the difference. I don’t think the weight is going to be much more. My friend has it on his 2016 and did a spring and shock valving change and all I can tell you is what a difference.
The class 10 bfg looks interesting. It's definitely very skinny. I would hope that leads to less weight in the tire. Looks like a strictly desert tire and would b pretty bad on East coast. Most race teams say that once 33+" tires are put on they gear the transmission way down to compensate. I would be extremely concerned of a 35 on a stock transmission gear set. Pretty sure that even with a clutch kit you could not get your peak rpms without gear reduction. As stated B4 once you go 35s shit will get real extremely fast on what the weak link is.
Just ordered my Vision beadlock wheels. Here are photos of the wheels and the “10 car” BFG tire I’m putting on. Once I get the wheels (30 +\- days) I’ll weigh each one and post weight of them vs stock.
