I'm assuming you got the 20" penta's in +25 offsets and I am also assuming you have them staggered at 20x9 and 20x10... if thats the case the 245/35/20 should be perfect up front.... the 275/35/20 should be fine for the rear.... most users here tend to go 30 series tires for 'i dont know why except maybe they like noisier tires.... but 35 will be fine... its only 5mm more

Here is another user with the same tire sizes
https://g35driver.com/forums/20-inch...mo-ecstas.html

one of the users sick03g is also lowered with a 11" rear... I think most users on this board run very conservative wheel fitments..... which is why you see most 20" users running 30 series..... so to answer your questions... 35 is fine.

PS if you're running higher offsets on your 20's than youre still in the clear.

 

so if I have 19" rims, I can cut these and put them on, right?

if I measure the circumference and cut the tires, how can I glue them back together?

Goop?
SuperGlue?
Staple Gun?
Silicone caulking material?

EDIT: OK I WAS JOKING!!! But no one got it!
