I was looking at some aftermarket wheels and noticed that a few had setup 19" in front and 20" in the rear and even 20" front and 21" rear... I was wondering if anyone tried that on their Aston Martin before and if so is it the front or the rear that the speedo uses for accuracy. Don't think it would be a good setup for track use but for regular driving??? Thanks

 

The speedo is only really going to be affected by the overall tire diameter. The speed sensors are in the front, so that's where it'll matter most. I don't think I've heard of anyone doing a larger diameter wheel on an Aston before.

 

Ditto.

Also, since I hadn't heard of anyone doing a larger diameter on the rear, I checked my system and I don't have a single Aston Martin with a rear wheel with a +1 on the diameter as compared to the front. Most orders I see are 20", a few 21", and a few 19", but primarily 20" just in case anyone was curious.

 

Thanks Rich/Jurrian for the info, I should stick with the majority when looking...

 

Yep. So if you go with a larger diameter wheel, just get a lower profile tire (if possible). Here's a website to help you determine speedo error after a tire size change: http://www.willtheyfit.com/

 

Definitely same diameter front to rear. - My thoughts: 19 for function - 20 for show - 21 is just too much

 

I like the 19" but found a very nice set of 20" made for the Vantage, still looking around but these are at the top of my list for now

Aston Martin Vantage
Front: 9.0 x 20 ET45 | Medium Concave
Rear: 11.0 x 20 ET38 | Deep Concave

 

forget about it. 38 is way off for the rears.

 

Agree

Mine are front 20x9 et42 and rear 20x11 et52 - this is for a Vantage

 

Thanks guys, I will talk to them about it...

Montana107, do you have a picture of your car with those wheels on, thanks

 

Now that you are contemplating wheels,


Are you still planning on running Continental DW's the Contisportcontact 5 or the new CSC 6's. Or jumping ship to the new PPSS=PS4 tires


I am in the same boat, like the Conti's and like the PSS's. Both rate top notch. Just wondering your thoughts.

 

Offset view

Absolutely beautiful. Very nice looking car. Perfect wheels with the correct offset.
These cars should have come with these offsets.

What size tires do have on those wheels?

 

Thanks Montana107, love the look... It must have been a misprint on their part as they are a high end wheel company in Europe... I have an email to them and will report back

SheriffDep, I love my Continental right now and was going to go with their new sport tire but I will have to wait and see... Still have to wear down those 19" first :-) only 10,000km on them
