As Josh mentioned, Nitto's have always ran narrow from my experience so you can shift the recommend wheel width rating to the left a 1/2". They should be rated 9.5-10-10.5". No way I would put this tire on a 11" wheel it would look stretched like a rubber band. 315's would be a must.


Here is a good read...This tire size is popular in the Hell Cat community.

So I got 2 of the 305 35 20s 555 IIs in today and they are by no means small. tread width is over 11 inches and the bead measures 11 and 3/4s. So they are on the big side for these and I think the 555s were smaller for sure. Tey look good I will try to post some pics later

Did you get them yet?

So I ordered these in a 305/35R20 from ebay thinking I could cancel the order. I then happen to find that Discount has them cheaper and they are only charging $20 for install and I can't find anyone around here that will install for close to that.

So I ended up ordering them from Discount in a 275/35R20 since after thinking about it I decided to be safe and order the stock tire size, even though I know I will probably regret it since the Nittos seem to be undersized and look narrow when mounted. I know a bunch of people on this forum have run the 305/35R20 on stock SS wheels and say they fit really good even though Nitto recommends not to according to their specs.

Apparently I can return the ebay ones, but im sure there will be some fine print somewhere saying I have to pay shipping back and it will probably be $100s. So I may have to keep them until I can use them (hoping they will fit on the stock SS wheels like the regular 555R).

Maybe I can get both side by side so we can compare them.

I am going to replace my Goodyear’s tomorrow with the Nitto555r2 305/30r20. The Goodyear’s were horrible at the drag strip. If all goes well I will be at the track tomorrow night and let you know how they worked.

Here they are, 305/35R20 W speed rated (I thought they were higher speed rated but apparently not):


I am tempted to try to get someone to mount one for me and I can measure the fit-up on car, but I wouldn't want to mess it up and not be able to return them.

I have never seen the 555R in person so I can't compare whats different.

What size wheels are you putting them on?

I put the Nitto555r2 305/30r20 on a 20x11 aftermarket rim. I had heard a few talking about rubbing issues on a 305/35 tire, so I didn’t want to chance it. I didn’t get to go to the track last night. But did try and get a couple runs from a dead stop, and no burn out or warm up on the tire. From a dead stop I had about a quarter second of slight spin Out of first and no other issues. I purposely throttled it to see what they would do, no letting off the gas. The 60 time was a 4.3 twice in a row. Hope that helps.

Thanks, was this a manual? I guess you were using launch control? Do you know how much pressure you had in them? With the variety of street roads you have around its hard to be consistent. From my testing I have found fresh pavement makes way more a difference that I thought, when you hit a clean, freshly paved surface it makes a huge difference versus a worn our road with loose gravel starting to come out on top. Obviously ambient temperature conditions make a difference, but I have found extended burn outs and trying to warm up the tires along with super low pressures (<30 psi) don't really help. I kind of want to try down to 10 or 15 psi, but I need to get my Chinese MDI clone out and working so I can change the tire pressure monitor warning threshold so it won't do any thing weird when I go that low and I can still use launch control.

Just get the damn things mounted and balanced already and enjoy the new found traction.

I have the 8 speed auto. I was on Highway that was not ideal for a great launch, and just smashed the throttle straight down. I was basically giving the tire the worst scenario with no prep. I would say they performed much better than the Goodyear radials I had. I am guessing with a little roll, heating the tires, or throttle control they will hook up with no spin.

awesome tires I will never go back to shitty MT street SS.
