bigger rear tires

[breoland]

I dont want to have to do any mods with the 11.75...if 11.5 is good enough i am fine with that. a 315 drag radial should be more than enough

I do not think you can run a 315 without trimming the bumpstop bracket. Especially since the 315 Nitto DR's are a 35 ratio which is 28.5" tall. A better 315 would be the Toyo 888's. They are a 315/30 which is only 27.6 tall. 28" is about max height unless they are skinny. If you do not want to trim the bracket you had better go 11" and run a 305.

agree with Lee. I have 11.75" rim and toyo 315/30. is nearly exact stock height and looks stock from side. I did have to trim bumpstop bracket and remove the dust boot from the shock. Toyos have an aggressive tread and look daunting from the back. Have pretty good bite.

Ron,

Are those the 888's? How do they stick? They look great!

[marsh2o]

I asked this same question about a year ago, the 10" move to the front........and no one had done this at that time. The 255's (at least in a P zero) seem a little small for the 9" front rims, so I'm sure they would be way small on a 10" front. I am not sure what tire size would work best........if the 10's did in fact fit the front.

 

My choice is to have the front 9's widened to 9.5 while widening the rears to 11.75/11 3/4". I still have a personal issue with cuting the only pair or set of Super Snake logo'ed Alcoa wheels that I will ever have for my car. I would almost prefer to buy the generic SPP Alcoa replacements and have them cut and widened, but then we are quickly heading toward the $4500+ wheel widening project that I mentioned in an above post. The extra set of wheels alone will be $2K plus shipping, and then $1600 + or - for the tires, plus shipping and then the $1000+ for widening front and rear, plus shipping. LOTS of $$$. All of this to preserve the "one time only" Super Snake Alcoa's.

I had some CS40 9" wheels widened to 9.875" and mounted PS2 285/20-20 on the front and they fit fine -- easily with enough room that I could have had the wheels widened to 10". I think the 10" Alcoas w/285/30-20 should also fit without any problem.

Thanks Lee. Yes they are R888.... seem to stick very well.

11'' wheel and 305/30, worked fine for me with room to spare. No trimming and did not have to remove the dust boot from shock. Lee called it right, thanks.

When you installed the 305/30, did your overall diameter get smaller by 1/2"? I researched the 305's a while back and found that while the 305/30 was the same diameter as the front 255/35's they (the 305/30's) were shorter than the original rear 275/35 by approx. 1/2", 27.2" vs. 27.7" overall diameter.

You are correct. The height is the hard part with a wider tire on these cars. The only two avalable sizes I have found that are wider and the right height is a 315/30/20 (same as stock height) and the 335/30/20 (1/4 taller than stock). Persoanlly I think the 28" tall 335 looks best from the side profile. Both of these will require widening wheels and trimming the bumstop bracket.

[dbackg]

Ok. You guys win.

 

So I am really close to pulling the trigger. I want to widen my SS wheels too.

 

11.25 to 11.75" wide?

 

Stock rim/tire setup = 27.7" tall = the stock SS rear is a 275/35/20. on 20" x 10" Alcoas

 

Considering the following rear tire setup.

 

1. Michelin 335/30/20 PS2. = 28" tall = Lee's setup Cost $491 ea

 

2. Toyo Proxes R888 315/30/ZR20 = 27.6" tall = BonDoc & Miamimtg setup - Cost $ 385 ea

Toyo's website states rim width = 10.5 - 11.5

http://toyotires.com...ern/proxes-r888

 

3. Dunlop SP Sport Maxx GT 325/30/20 = 27.7" tall - cost $806 ea

rim width 11"-12"

 

4. Pirelli PZero 305/30/ZR20 = 27.2" tall - max rim width 11.5 - cost $ 333 ea

rim width 10.5 - 11.5

Hope you don't find me jumping in for some corrections here

 

stock tire is 27.0

 

305/30 is 27.2 tall

 

315/30 is 27.6 tall (R888)

 

335/30 is 28.0 inch tall,( not sure why you say 1/4)

 

and there is a 3rd avail tire, 325/30 which is 27.7 tall.

 

Hope this helps.

stock tire is 27.7 - Pirelli PZero - 275/35/20

 

305/30 is 27.2 tall - Pirelli PZero

 

315/30 is 27.6 tall (R888) - Toyo

 

335/30 is 28.0 inch tall - Michelin

Who makes the 325/30/20 ?

[BoneDoc]

Who makes the 325/30/20 ?

 

Dunlop.... about $800/tire. i would have bought this one but thats too much for a tire in my opinion.

duh. I posted that earlier ... already wiped it out of my mind. ha. lol.

 

Agreed. Yes $800 each is way to expensive.

I went 11.75 at Lee's advice. This way you have the option to go 305 to 335 if you want. I am currently running 305 P2's because I got a good deal on them. When these are done, I will need a full set and will change to 275 fronts and 335 rears. The 305's did not cause me to trim the dust boot. I did have to adjust the panhard bar as my car was not perfectly centered and it rubbed alittle to the offset side. Once centered I've had no rubbing issues. The 305's are a HUGE improvement over the 275's, but you still can melt the rubber in 1st and 2nd if you are aggressive. I think the extra tire at 335 will help even more.

I'm surprised that the michelinman.com site does not show complete information for their tire specs. I see the recommended rim with for this 335/30ZR20 is 11.5" - 12.5" and they show a section width (sidewall bulge) of 13.5" "On measuring rim width", but I do not see a mention of what with that "measuring rim width" is, in the 11.5-12.5 range. Tire Rack gives a more complete spec. They list the same info. as Michelin, but they also show that the measuring rim is 12" which means on a 12" rim, the sidewall bulge (section width) will be approx. .75" on each side for the 13.5" total. They also show that the actual tread width of this 335 is 12.5", so the tread itself (not including the sidewall bulge) is approx. 1/4" wider than the 12" measuring rim on each side. Of course if the rim is narrower, like 11.5 or 11.75, the bulge will be a little more and the tread will overlap the rim more, but moving from a 12" to an 11.75" will basically be an additional 1/8" tire bulge on each side, an 11.50" will add 1/8" more to each side.

I am interested in the fact that a specific tire fits a rim, or rim width range, but I am also interested in how it fits................ a fat/bulgy look?, or flat sidewall?, etc., and then will the overall tire diameter change the way I use my car? Will I be able to use my four passenger Super Snake as a four passenger car? or have I installed a taller tire on the rear (which serves the traction purpose), but because the tire now rubs the fender under certain conditions, I am limited on who or what I can haul in my car?

 

I want more rubber, but it has been identified that a tire of the 28.7 or so overall diameter will contact the rear fender and will require the car to be adjusted higher. This defeats the purpose/look of a lowered four passenger Super Snake.

OK, this is the question I have, which Lee wrote but was not answered. If we go with 11.5" wide Alocoa and a 305/30/20 tire, will we need to trim the bump stop or shock boot? Or is 11" the widest? I don't want to cut anything up on my KR or effect the ride with a passenger.

Thanks,
