What is the biggest difference between running 20x10+35 on the rear compared to running 20x10.5 +27

I'm really new to this so any help would be appreciated. I have been looking around. Is the concave of the rim deeper in the 20x10? Could I still run a 275 back tire on the 20x10.5?

The 20x10 is on back order and I know where I can purchase 20x10.5 right now. The waiting for 5 weeks while I have the 2 front rims sitting at my house kinda sucks.

I have a 2008 G37S coupe. I'm running 20x9 +27 in the front. Thanks in advance

 

what's your suspension?

 

Your fronts are 20x9 +20 and I would go with a 20x10 +35 with a 275/30. I would probably wait the 5 weeks. I thought that the 10.5's were backordered not the 20x10's. Double check that, call around to all the wheels distributers to check their stock. Get your wheels isnt the only place that carries them.

 

I have called 6 different places I could get numbers for on the 20x10. All back ordered. Just leaves me kinda stuck.

 

EliteRoads - in ft lauderdale.. they had 10.5's last week..

 

Concavity-wise, not much different.

The 10.5 will extend 14mm more outwards, but also gain you 2mm more suspension-side clearance.

The 10.5 will also weigh more.
