Tire rack shows 18 manufactors making 305/35/20 to include the popular Michelin, Conti, Firestone, Goodyear, Pirelli. Are you sure you didn't mean your comment towards a 305/35/19? OP asked about 20" in rear and 19" in front. 305/35R20 are run by many of us on here.

305/35 is not at all common and will significantly crimp your options. Why not just stick with 10" wide and use 275/40 or 285/35 at each end?

For those that want to see the "Math" and comparison...I used my 2018 GT350 and the OEM on the 2021 GT...going with the 20 Rear 305 and 19 Front 285...this will avoid me needing to lower car and get a slight rake look.

305/35/20!! Yikes thats a tall tire and huge discrepancy between the front and rear heights. A 285/35/19 is 26.8" tall while a 305/35/19 is 28.4" tall, that is no bueno, this could cause issues with the AdvanceTrac. You should be running a 305/30/20.

LOL...I will let you know, but I did a taller 20" setup on my 2015 no issues at all...

You can do 20" setup, but the difference between the front and rear may be to much. I read the front and rear can't be off by more than .5" or it will cause issues with the stability control. It should be a 285/35/19 and a 305/30/20. This is within the .5"

Never heard that before...its only .85...and is the look I want a more old school Rake...the 30 profile would look sagging IMHO...again, if its a problem, ill switch the rear...Again never knew this .5 delta front to back...need to read up on this for sure thanks.

No a 285/35/19 is 26.9" tall a 305/35/20 is 28.4" tall...how .85"? 28.4-26.9 is 1.5" difference. Like I said you want to get a 305/30/20.

I posted an image above with all the calculations...OEM is .6 already Above Rear to Front Front 27" rear 27.6" new set up would be 26.92 Front 28.42 Rear so compared to OEM I am down (0.08) on Front and Rear up .82...I have been doing all compared to OEM. So I get what you are saying for sure but delta from OEM Rear to Front is not as drastic. Again I have been using OEM ratios...in the end Ill either love this or hate it. I definitely don't want or like when the rear looks like it is smaller or sags to front. Personal preference.

The PP1 cars are 0.7" different front to back, just throwing that out there.

I wrote this in regards to the "more than 0.5" upsetting the traction control" remark.
It will be interesting to know if your size difference increase will do anything wierd. Looking forward to seeing your results.

Oh yes I understood...and agree I will now be .9 total opposed to what you have pointed out was .7. so I was agreeing my gap is now only .2 to my assumed .3 LOL...Yeah, Paul is great to work with...he wouldn't let me go too crazy so I may have an issue, not sure I will as so many guys are running the 20x11 sever with 305/35's...It may cause an issue wont know until I at least try. I will update when I get wheels. Again thanks for the clarification.

Hi all...I have spent HOURS looking for a combo that does NOT lower the car, so keeping OEM ride height and using a Stagger / Stagger to get a rake look and fill wheel wells out. This is on a 2021 GT Premium. Will be doing Forgestar CV5's...if anyone has done this or similar can you post a picture please? Hoping to use MPS4 - 20x11 Rear 305/35/20 - 19x10 Front 285/35/19 Stagger / Stagger..Thanks in advance. I did a similar to a 2018 Mustang and used same wheels on my GT500 but this is a tad different since I am not putting on a GT500 now...

Paul @PKAUTO again did a KILLER job in helping me order, and deliver a BEAUTIFUL product. THANK YOU Paul. This will not be for all, but it is IMHO a unique, different and rather cool setup...20's rear and 19's front. Goal was to create a small rake without messing with springs and fill wheel wells up a little more. Also waqnted to keep profiles of front and rear equal...could have put a 40 up front but then it would create more sidewall.

Paul@PKAUTODESIGN - is a ROCKSTAR!!!!!
