Are these alignment specs unstreatable? |

Thanks! Well, my concern was wear and how it may effect how much my steering is for the streets. Caster was just a big surprise to me. But i made up for it before I found such info, so the surprise was more noise than bite. Well I think I am well settled on the matter. I think for the fun of it, i will obtain 10.5x17 for the rear so I can use the 315/45 tires. Though I had to pick an not so popular SVT rim, that seems to be unique enough, only a few options are available for aftermarket. The NOS factory rims I have doubled in cost, if you can find them, since my purchase over 13 years ago. Most are going with 18 and 19 inch rims like you. Though 1k for tires is what I expect any way for myself. I have 18 inch rims on our Honda and find them a bit less forgiving in the streets, as for bumps and pot holes. Our outer lips on the rims are chewed up. Something you may realise or not on how your streets are. |

Where are you finding a 315/45-17 tire? The main reason I am looking at the 18 is sheer volume of tire size available.
For the most part we have pretty good streets. I attribute that to the mild winters with limited snow/ice since that seems to really tear up the roads. I also don't drive it daily so that is another factor. I have definitely been waffling around on the wheels that I want. I wish there was a better place to search up multiple rim styles in the size and backspace that I need. Best I have found so far is Summit but most in the size and backspace also seem to lean toward being truck wheels. I wanted minilite style but I am having a hard time reconciling the cost on those. |

Haven't looked up as of recent, but here are some tires. Pirreli P Zero p275/45r17 are still available Mickey Thompson had p275/45r17 street strip tire Nitto NT450 Extreme 275/50R17 - may work for me There are others I may have to search and find. Looks like older 45 and 50 series are drying up. May have to move Into the 40 series or go into the p255 to get 50 series to work better on 17 inch rims. Tire rack was my goto long ago, but there may be pers now like discount tire and tires America. Will update once I get rolling on my tire searches once more. Found an old link... Seems like racing tires are no longer made for my rim. Here is Ford racing's info. https://www.oemfordpart.com/oem-parts/ford-p315-45zr17-7v-9oo1389045106 I give up on the 45 series street track p315 tires. Will have to do the odd p255/50 stretch to match a p315/35. Not gonna happen until I get two 17x10.5 rear wheels to match my SVT wheels. At least ture rack still stocks good tires for p275/40-17 sizes. The Michelin Pilot Sport PS2 is another option for my list. Edited by 304-dude - Jul/27/2017 at 3:17pm |

Ok, so it seems you are running into the same thing I did when trying to find a good rim/tire combo. The tire selection gets really limited in fatties for the 17" wheels.

Well seems like if you keep it around 275 for 9 inches, you must put on 40 series. Unless you want to find 255 in 50 series. Which are stock on Mustangs with 17x9 back in 2002 to 2004. I may have to shell out some coin and get 10.5 wide rims that look like the 10th Anniversary SVT rims, if I want the 315s on my rear. Or one can run strip tires and have a custom tread done to help with rain conditions. I can't believe a niche market (drifting) has made mainstream tires so pimped at 35 on down or 20 series for wide treads. I just don't like 94% rim look on cars. The Japanese marketed drifting to sell more cars, and sell tires. Now everything is built around low profile tires and big rims. Well, I should not talk, the California look of the 60s and 70s came from the drags. Just never seen companies give into dropping a market segment so sharply like the 17 inch rims. If 14 and 15 inch rims were done that way, nobody would be driving with proper sized tires on their rims. At one time someone talked about using metric tires. Though that discussion was away back and have no clue now as to sized tires they needed. |

Shootest, I found a source for my 17x10.5 10th Anniversary SVT wheels.
Since I now am contemplating doing them on all four corners, due to how my custom steering and rear is setup, I may be the only AMC outside of JersyJoe's AMX to run wide rims on all four corners. I do plan on having the wheel arches flared with a custom 70's mod look. Now I am thinking it's probably time to sell my NOS Ford Racing 10th Ann. Cobra SVT rims to collectors or clone wannabes. Here the link if you are interested in seeing them. https://www.americanmuscle.com/anthracite-10th-17x105-9404.html |

You guys are running into the same issue I did with the 17" wheels. The largest competitive autocross tire in 17" is 275/40/17. I currently have a 275/40/17 on 17x9.5 front, 315/35/17 on 17x11 rear. So I'll be able to upgrade fronts but I have no option for the rears. Will probably have to go to a 18" wheel which is a bummer.

Geeze, I am starting to feel 18 inchers is a forced option. 18 is just not to my tastes, and luckily, I will not be all that about competitiveness with tires since track time is optional. Though there is that option street wheels and tires for looks, and odd looking 18s for competition. |

I am starting to tare myself away from the 17" rims and my love for the 10th Anniv SVT rim look.
I have been juggling offsets and backspacing between 2004 and 2015 Mustang. My spring distance with stock suspension hump and a 1-1/2" spacer allows 6.75" between tire and rim with some room to spare. Oddly enough there is room with 2004 rims to fit without the spacer. My use of spacer was to make the front 65" wide on its track, keeping front and rear equal. Here are the wheel specs for non staggered front rear with widths of 10" (2004) vs 10" (2015) 2004 Mustang 10" wide rim 0.86" Offset 6.37" Backspace 5.25" + 0.86" = 5.86" (More than enough room with my suspension hump mod of 7.00" distance between spring and rim.) 2015 Mustang 10" wide rim 1.65" Offset (May not clear rear leaf springs on stock rear ends) 7.15" Backspace 5.25" + 1.65" = 6.85" (Cuts it close with my suspension hump mod.) On the plus side of using impossible 2015 rims, is less need for huge bulging fender flares. Though, it will shorten my track width very close to 64" wide. Just so happens it fits within 1971 SCCA rules for T/A racing. Never would have thought about changing over to newer rims, though everything was built up long before there was an option. Here is a picture of what rim I am allowing myself to accept the blasted 18" rims. Now finding a nicer tire option should not be so difficult with having more variety. |

Since you like that particular look check out the US Mags Rambler wheel. I love the look of it.
