Have any owners of a 2015 era Vantage V12S tried to increase tire size on the rear to aid traction? What were the results?
TIA

 

on my 2009 I went with HRE P101 19x9 ET40 in front with 255/35R19 and 19x11 ET52 at the rear with 305/30R19, I believe you also have 19x11 wheels at the rear so 305/30R19 will fit for sure and maybe even bigger due to your offset of ET68 vs my ET52

 

Thank you! Any issue with the computer with the increase in tire size at the rear if I keep the fronts the same?

 

No issues and now with the 305 when I see the electronic speed sign it shows exactly the speed on my speedo... it was a little off before, lol

PS: remember my car was OEM Front: 235/40ZR19 & Rear: 275/35ZR19 at the rear so a very big jump for me... you are only going from 295/30R19 to 305/30R19

 

Thank you for your help.

 

Did you consider going up to 265 for the fronts so you’re +10 on both front and back?

 

I did but at the time the 265 weren't available so maybe next time which is probably next summer I will try 265 front and 305 rear

 

I have the stock forged 19’s on my V12VS and I plan on fitting 265/305 PS4S’s when my current P Zero’s expire

 

Would there be an issue with clearance if the fronts were larger especially in hard turns?

 

There are several people running 265 front but I am not sure if any are running those on OEM wheels. I have a set of HRE P101 with a different offset than OEM so for me it should not be an issue

 

Thank you for your help.

 

FYI:

I'm currently running 21” Rear & 20” front VS Forged Wheels - Front Wheels with Michelin PS4S 245/35/20 Front & 305/25/21 Rear with some extreme offset. I bought the wheels used for my V8 Vantage and they worked fine - no rubbing issues, but to clear the rear brakes I had to add a 1/8" spacer - when I switched the wheels to my V12S (temporarily) because of problems with the stock wheels on delivery no issues on the V12S. The wheels look like the 2025 Vantage wheels and look fantastic, but the diameters are quite a bit larger than stock, especially in the rear. I really wanted to keep the stock wheels which look fantastic, but the dealer powder coated them in a dark grey before shipping to 'fix' scratches, ruining the look of the car. Anyway, I commissioned the Aston Martin Wheels from Forza Forged in a 20" diameter with some extra offset for a more deep dish look and eliminate the need for spacers.

I won't have the wheels (actual pictures below) till February, being shipped from China, so I won't recommend replicating what I ordered until I'm 100% sure of fitment. I also show below the tire/wheel fitment compared to stock on the graphs below.

 

Thanks. Looks good!

 

That's cool, I had come across this company before but was sure of legitimacy. So you're basically getting Vantage V12S wheels remade in a better size/offset? Would love to see the finished product. Do you know if they are forged or cast?

 

They look great, hopefully the quality match the look
