Will 275mm Drag Radials fit on Kosei K1's (15x7)?
 

I currently have 26x10.5x15 MT ET Streets on 15x7 Kosei K1's and I'm looking to switch to drag radials this summer. I'd like to put on some Nittos, but they only come in 275mm. Has anyone tried putting 275's on a 7 inch rim?

The minimum recommended rim width for the Nittos is 7.5 (according to Nitto's site) and the min recommended for the MTs is 7.3 (according to Summit).

Thanks in advance for your help.
