Wheels and Tires!!!!
Skinny’s all around!!!!
The most recent addition to my P520 are the ITP Ultracross R 27x9-14 tires and 14” Raceline A95 Trophy (4x110, 5+2) simulated bead lock wheels in Gray/Black.
When I began evaluating my tire options, I was totally flummoxed. There’s just so many variations and possibilities! Just looking at the tread options and tire sizes was enough to make my head spin. They’re endless! I like options but, come on, this is ridiculous!
I began narrowing my choices based on usage. I don’t use my P520 in the sand, for rock crawling, muddying, or wading through water. I mainly use my P520 on my property and recreationally exploring trails in the local forests. Since I realistically have no need for extremely aggressive tires I decided to go with a more traditional A/T tire tread design.
My biggest complaints with the P520 are the low gearing, immediate shift points, the shameful top speed, inaccurate speedometer and rough ride.
To help remedy these issues I chose to go with a taller tire to extend the gearing, help raise the shift points, correct the optimistic speedometer, enhance the top speed and perhaps, even improve the ride.
Will taller tires be enough?
In a perfect world, I would have gone with a 28 inch tire, or perhaps larger. But, I didn’t want to add wheel spacers, control arms, a lift kit, or encounter any rubbing issues on the frame, or bodywork. Plus, the bigger you go, the heavier the tire, which can cause unfavorable performance characteristics and the taller you go, the higher the ride height, which can increase the risk of a potential rollover. Furthermore, I’m trying to keep my P520 as close to the factory 50 inch width as possible and you can’t do that with enormous tires. Additionally, unlike the factory setup, I want all four tires and wheels to be the same size, so I have the ability to rotate the tires and carry a spare if necessary. Well that’s a mouthful.
Taking all of this BS into consideration, I decided a 26 or 27 inch tire would be the best compromise.
Naturally, I conducted a fair share of research before I pulled the trigger on the ITP Ultracross R tires. I probably spent far too much time visiting online vendor websites trying to put together the best tire combination. I found the most help here, on the HondaSxS Club simply reading threads in the P500/520 Wheels and Tires sub-forum and also from various member build threads. My decision to purchase the ITP Ultracross ultimately came down to several positive reviews, tire availability and a special Labor Day sale price.
As far as wheels go, I would have been happy sticking with the stock 12 inch wheels. But, I was having a difficult time finding four 27x10-12 ITP Ultracross tires in stock from a single vendor. When I was lucky enough to find one available, the pricing was utterly absurd. For some reason or another, they were more expensive than the other sizes. Most importantly, however, the 27x10-12 were wider than I preferred. I really wanted a 9 inch wide tire to curtail the overall width of my P520.
Unfortunately, ITP doesn’t make a 27x9-12, only the 27x9-14. So, upon that incredible disappointment, I decided to go up to a 14 inch wheel size, which meant, new wheels! Honestly, I would have been totally fine with 14 inch steel wheels but, it’s easy to get carried away. As luck would have it, I found the Raceline A95 Trophy 14 inch wheels on sale, which was all the motivation I needed to make the decision and purchase them.
Enough talk, let’s see the pics!!!
I’m a little bummed that the Raceline wheels don’t match the Gray P520 bodywork. Yeah, I’m that anal. But, with all the dust, dirt and grime collected from riding, I’m sure it won’t bother me for long. However, if it continues to bother me, I’ll pull them off and paint them black.
All things considered, I’m pretty happy with the appearance of the complete package.
During my research I read that the ITP Ultracross R tires are undersized and that they are not as tall as the manufacturer specifications claim. It is rumored that the ITP Ultracross 27 inch tire, actually measures 26 inches in height. Really?
They look pretty tall to me!
When these tires are mounted on wheels and inflated to 20-30 PSI, they measure very close to the 27 inch specification. However, when they’re inflated to a more realistic 8-15 PSI, they measure closer to the 26 inches. I’m still playing with my tire pressure but, with all four ITP Ultracross tires inflated to 10 PSI, I measured a full 2 inches of additional ground clearance at all 4 corners.
I gotta say, the claim that the ITP Ultracross tires are undersized, ultimately proves to be correct once the tires are mounted, installed and inflated for practical riding conditions on the P520.
The factory P520 tires are 24x8-12, front and 24x10-12 rear. With the new 27x9-14 ITP Ultracross tires all the way around, my P520 now measured 52 inches wide in the front and 51 inches in the rear. I really didn’t want my P520 any wider but, considering the size of the new tires, these results were expected. I may actually add some rear wheel spacers to balance the front/rear widths.
Thoughts?
I was given the green light on this tire/wheel project by my better half. She was constantly complaining about the rough ride on the trails and on spirited rides around the property. I promised the larger wheels and tires would improve the ride quality dramatically. Well, that was a false assumption. Don’t get me wrong, the ride is better but, only marginally better than before. Hmmm, I bet shocks will do the trick!
The new larger diameter tires have helped the gearing. I believe the new tires actually make two full revolutions before the shift into second gear! All kidding aside, yes, the gearing and transmission shift points have improved a bit and the speedometer reading is in fact, more accurate.
When stock, my P520 would show an indicated 40 mph on the speedometer, while my GPS was registering 37 mph. Now, with the new 27 inch tires, when the speedometer is showing an indicated 40 mph, my GPS is reading 41 mph. That’s a bit more accurate than before and the top speed has increased by 4 mph, excellent!
I read from several sources warning against adding larger tires and wheels to a UTV stating it will hurt the performance because of the extra weight. Seems logical but, I believe a lot of these concerns originate from folks that haven’t driven, or experienced the torque and super low gearing in the P500/P520. The P520 isn’t a powerful machine but, I can’t fathom how a larger wheel/tire setup would significantly effect the overall driving performance.
I didn’t weigh my new tire and wheel setup but, this new combination is definitely heavier than the stockers!
As far as performance goes, the steering effort has increased, but remains totally manageable and when driving up steep hills I can sense a little sluggishness which is quickly resolved with a little more throttle input. That’s it. In all other driving conditions, my P520 feels better. Above all, it’ll still do donuts and it continues to accelerate strong from a stop. Without a doubt, there is no significant loss of performance.
All in all, I’m very happy with the new wheels and tires. My P520 feels, looks and rides better which is always a good thing! And, I can’t argue with a little more speed and riding performance!
