Racer_X, Like I said..sry not ranting on you personally..I applogize for if this comes off as "Hater" talk..in no means am I a "Hater" of you or any Aston owner..if I was, I wouldn't be spilling my years of Aston Martin trained knowledge to everyone on this Aston forum for free..I help because I love the Brand and helping out the owners best way I can..

 

Irish07, just wanted to publicly thank you for all the knowledge you share with us here on 6spd. Every time I see your screen name on a thread I make sure to read it. Your input is greatly appreciated and I have learned a lot from your posts. Thank you.

 

I was hoping to read some posts about calling a tow truck. But even those aren’t safe, they can damage the bumpers. So then what do you do? Some flats cannot be temporarily reinflated (if tire fell apart)

 

I have a Dynaplug Pro Xtreme kit because I don't want to find myself in the middle of nowhere with no opportunity to limp to a hotel or garage.
I've never had to fix a roadside flat with it (fingers crossed!) but I did find myself with a flat in my garage. My tire had a deck screw in it and it had deflated over a couple of days.
The Dynaplug did a great job of plugging the hole, which allowed me to drive my car to the tire shop so they could replace it. It was easy and lost no air over a three-day period in my garage or a 30-minute drive to the store. Why didn't I just remove the wheel and take it over in another car? Well, they couldn't match the tire, and it was time anyway to get a set of Pilot Sport 4S!
I carry the Dynaplug, a small inflator, and a compact scissor jack with some jack pads in the car.

 

I may have missed this while scanning though the thread but I’ll ask anyway:

Are there any spare tire options for the Vantage or DB9?

The best I could find after a google search was someone on Jalopnik claiming he used a Lexus spare tire (not specified which model) and it fit on a Vantage.

 

It hasn't happened yet but I guess if I were to get a flat it would cost me two new tires. Maybe four better tires.

 

I'd love it if mine had a built in factory space saver, because I've never had a car that didn't have a spare and only a fix-a-flat kit. But I don't want to give up the room in the hatch to carry one, and a jack and wrench also.

 

Call AAA. Happened one hour outside of Reno. Tire Rack delivered a new tire within an hour.

 

How did they mount the tire on the street? Or was it towed first?

 

Called AAA and asked for a flat bed. A shop in Sparks changed it. Fender and rim was undamaged. All that black stuff on the ground is powdered sidewall that fell out of the tire when we stopped.

 

Even if I had a spare, I would call AAA. Rather use their tools to lift the car & swap the tire

 

Ford Part #BR33-1007-AB is a 5x4.5 bolt pattern 18x4.5 inch ET40mm space saver spare wheel that if fitted with a 135/80/R18 tire (common in Jag space savers) will have a final circumference of 83.2inches / 26.5" diameter. The rear wheel is the only one you really need to worry about matching, the 275/35/19 rear wheel in the DB9 has a total circumference of 83.5inch or 26.6" diameter. Although Aston doesn't specifically give us specifications for the max variation between left/right tire for the limited slip diff, a difference of 0.3inches (or around 9/32") in total circumference or a 0.1" (4/32") difference in overall diameter is at the limit of the spec provided by most AWD car manufacturers.

From the specs I can find online about max tire wear/variations on AWD systems;

Audi - 4/32" of each other
Porsche - 30% of tread life (so e.g. a new tire of 10/32 could be matched with 7/32 so a difference of 3/32 or 6/32 in overall diameter)
Nissan GTR - Each tire must have 6/32 of remaining tread depth (so e.g. a new 10/32 tire can be matched with a 6/32 tire, a difference of 4/32 or 8/32 in overall diameter)
Subaru - 2/32 of each other tread depth ( so 4/32 in overall diameter)

Given these are AWD systems and thus the spec will be much restricted than what would be acceptable with a RWD car. Since with a RWD car the rear tires cannot articulate like the front wheels and thus wont see such tight radius of curvatures like when turning at an intersection or something.

The only question is if this combo will clear the front and rear brakes. Worst case could put 1/4" spacer on it. I guess there is only one way to find out!
