I know that there are a number of people talking about how to put on a larger tires on there ss. What is the largest tire I could put on my ss with ford racing suspention. 295 305? What are the best brand. Thanks

There is some good information on this subject in the 40th anniversary forum.

Here is some info. and pictures of a 305 install on a 10" Super Snake wheel, on a Super Snake. It all depends upon the look you desire, once the tires are installed. If you want the tires to tuck (or at least not stick out), it will cost $$$. If you don't mind them sticking out a little, 305's do fit the 10" Alcoa rim nicely......................

If I remember correctly, the rear are 275/35's P Zero's?, if so, they are 27.7" tall, 295's are only 27" tall, and then the 255's on the front are 27.2" so the rear 295's would be shorter than the front 255's.

I did a search of all major brands handled by Tire Rack, I realized why Pirelli P Zero's were chosen.........they offer the widest selection of 20's that I could find in this range.

If you widen the wheels you can go all the way up to a 335/30/20. You will have to do some work to make them fit, but its been done. Adjustable rack bar is a must as well as trimming the bumpstop bracket along with moving the rear shock slightly and removing its dust cover. Wheels will need to be widened by 2" from what I can tell. Will let you know for sure when I get mine finished.

Widening will give you inward room for more rubber, but does not help for the "out to the edge" fit of the original 10" Alcoa wheel and tire. The wheel/tire assy. will still be out to the edge of the fender lip (and past with some rubber), and the widening will only add width and rubber toward the inside. It would take a complete redesign of the wheel offset to tuck the rubber, .................................or a shortened rear axle.

Adding 2" more rubber and 2" more rim to the inside should keep the outside rubber right where it is now. Currently the SS has a 10" rim and a tire that has a 11" section width giving a .5" bulg on both sides. I am moving to a 12" rim with a 13" section width which will also have a .5" bulge on both sides. Out side of the tire sould not move.

And this will depend on the specific tire manufacturer. Not all tire widths are measured at the same point on the tire, some are measured where the tread breaks over the edge, some are measured where the tread stops and the sidewall begins. This is why some tires of the same size are wider than others of that same size but different brand. There is no standard in the industry as to where the tread stops for width measurement. It all depends upon the specific brand of tire and where they measure their width. BFG's run wide, Nitto's run narrow when comparing same size tires. I personally know that a 255/45/17 BFG Comp T/A is much wider which also means the height is different when compared to a 255/45/17 Goodyear GS C. <<Both tires are the same size, but the 255/45 Goodyear fits nicely on a 17x8 rim and is small on a 9" rim, the BFG Comp T/A is too large for that 17x8 and fits much better on a 9" rim. They are both 255/45/17, but they are way different in "real world" size. This will also be the case with 20's, they vary in size, some by quite a bit.

Yes if you keep widening the rim toward the inside, and don't get too wide with the rubber, the sidewall look will stay close to what it was originally with the 275. Personally, I like a little bulge (but not too much), and the original 275's on the Super Snake 10" rim seem to be more flat. If the tire begins to bulge much at all, the tire will get past the lip. <<<And then we are back to the same issue that we started with, tire past the fender lip and the "too wide" look.

And then we are back to the same issue that we started with, tire past the fender lip and the "too wide" look.

The section width on the tire I measuered were the ones I am going to use of coarse (the PS2 is the only tire I found made in that size). The 335's are Michelin PS2's and the SS tire is the stock Pirelli. The issue we started with was "what size tire will fit". A 335 should fit with adding 2" to the inside of the wheel, a adjustable track bar, a little work on the shock and trimmimg the bumpstop bracket. Outside bulge should remain the same.

Yes, the thread did start with "what size will fit". I was under the impression that the person starting the thread was asking what tires would fit on the stock 10" Super Snake rim. I did not see a mention of "wheel widening", so I replied as to what fits the 10" rim first of all, and the "look" that will be achieved with what fits on the 10" rim once the rim and tire assy. is mounted on the car.

I went out and glanced at my Super Snake, and there is really no bulge to the 275's, they are basically flat with the Alcoa and if the car were to be lowered futher (with the Shelby/Eibach), the fender lip would be on the tire. Any additional bulge (wider tire) would put the tire out past the fender lip, and any lowering would still put the car on the tire. The only way to remedy this is either to have a Super Snake wheel redesign in the mounting area, or the shortened axle. The tire has to be pulled in, in some way.

If this person is interested in what will fit, sticking out past the fenders at all, gives the appearance of "not fitting".

This is the view looking straight down the fender, no room for additional bulge there, not even 1/2". If there is any additional bulge, it will be considered as not fitting properly by most.




Here is a view with the rim surface............even with the 275, the rim and tire are out as far as they can go without looking "big".



The only remedy to get a larger tire (with a bulge) on this 10" rim, and keep the car looking, well, nice for lack of a better discription, is to pull the tire/wheel in. Anything else larger is going to stick out. Some people are into that "wide look", and that is fine, but then we still have possible tire/wheel lip contact issues. Nothing short of pulling the tire/wheel in, is going to fix that.

I posted about the SS on another forum and they talk about how small the rear tire is. Someone hasn't realized it needs bigger rear tires to put all that power to the ground.

-----------------------------------------------

This has been discussed from the very beginning^^^^^^^^^. There was mention of a 11" rim (I assume with a different offset), but it fell through.

The thing that many non-Super Snake owners do not take into account is the fact that the Super Snake also has rear brake duct work (like a Z06) and that rear brake duct work will not allow for any additional tire width on the rear. So, the Super Snake has as large a tire on the rear as will fit with the rear brake ducts that were designed for the car.

Lee - I noticed that the 335 that you have mentioned is .4 shorter that the 305 P Zero and about .3 taller than the 275 P Zero so height wise it will be a nice fit. The only issue is to get such a tire to not stick out past the rear fender lip, and unless a flat sidewall profile is achieved, as is the case with the 275 P Zero on the 10" Alcoa rim, any bulge is going to make the tire look "fat" if it sticks out.

Wow, a 335!! That would give some traction!!

If you widen the wheels 2" to the inside, the out side tire buldge will not change. You are adding 2" more tire and 2" more wheel to the inside. All the extra rubber will go to the inside of the car. You are correct that the rear brake ducts will no longer fit, but I would preferr the wider tire. The PS2 335/30/20 looks to be the perfect tire. On paper it works out perfectly. Just have to see if it works on the car. I am looking at atleast 3 weeks on the rims so I will let you guys know how well it works. Only thing for certain is these cars need more tire!

Even with the 305's I think the rear brake ducts are out, especially if the axle is shortened. I am interested in your project. Are you widening your original Super Snake 10's? or a pair of the SSP catalog replacements?

You are correct. I went with 10.5 on my razors with 305's and tried and the brake ducts had to come off.

Sorry I have been lazy and have not posted anything. I widened the stock SS wheels to 12" and slapped on a set of 335/30/20 PS2's. They look awesome! Fit perfectly. Can not even tell untill you get behind the car. They only stick out max 1/16 of an inch more than the stock 275's from the fenderwell.

One of the wheels did not ballance quite right so I had to send it back to Weld Craft. Have not gotten it back yet so I have not been able to test drive it. Once I get the other wheel in and mounted I will take several pics of them on the car and post it. Been focused on getting everything ready for the Texas Mile so the street tires have kinda been on the back burner. Here are some pics of the wheels and the one I have mounted. Should make a slight difference in traction!

Can i get a pictures of them on your supersnake. Just got my car back last week just have about 100 miles on it since returning from vegas. Thanks
