I want to go up a size but not to 22’s since some have stated that performance has been impacted when going to 22’s. If you have not noticed a difference, let me know what your setup is. For now, Which 21” tires would be the best? Thanks.

 

I'm running 265/35/21 Fronts, and 315/30/21 Rears. I can't really say if I noticed any performance lost since I don't track mine. It does feel a little more agile but that may be in my head. It originally came with winter tires on the stock 20's so I'm not sure what it suppose to feel like originally or what the performance numbers are suppose to be.

For people running 22's, most don't feel the difference anyways unless they actually tested their Panameras on the track with both stock wheels and when they're on 22's.

And I thought 19 was already too big.

 

I just got a set of 21's, huge thanks to Deezflip by the way for helping me dial in the specs just right. I will be getting the same tire sizes he's running (Continental, my friends gets a discount). Can't wait to get them mounted up.

 

i think I’m about to pull the trigger on a set. Mind sharing your offset? I hear +45 front and rear. I definitely want to get it right the first time.

 

Thanks for the info! What offset did you go with on your 21’s?

 

Glad to help!

I'm running spacers, but my final specs with the spacers are...
Rear 11in wide, with 315 tires at et49
Front 9in wide, with 265 tires at et40



I don't have a close-up of the front fitment...

 

21x9.5 et45
21x11.5 et55

I'm thinking maybe should've gone 11" rear with et50, so I wouldn't "have to" buy a 315 series tire, but I did also wanna stick with stock wheel widths so it's whatever.

Super pumped for this! Signature SV107 finished in brushed clear.

 

Nice! I think 11.5 gives it a more concave look to the spokes.

I actually wanted to go 335 wide tires...but it would be too much on a 11in wide rim. I could rebarrel the wheels to 11.5 or 12, but I'm content to what it is and not sure if I want to put any more efforts into it. If you wanted to go narrower tires...295 or 285, it should be ok on 11in

 

335? Holy hell!

My friend's discount is only on Continental tires, so even though I looked at 285/295, Conti doesn't have an offering for 21" 30series tires. So I'll just stick with what saves me money for now and look elsewhere when the time comes. Probably will drop to 295 or 305 on the future, as I think 285 on 11.5" might be more stretch than I want.

 

If you ever need to drop tire widths in the future, 285 on 11.5 might not be a stretch at all and 275 on 11.5 is when the sidewall really starts to arch inwards but not extreme either...
