Tire help for 215 20"

[lpicota]

I´ve been searching and was thinking about the Dunlop Sport Maxx runonflat 275-40-20 front and 315-35-20 rear, since my E-70 has the third seat row and not being able to place the spare tire kit.

At the same time I´ve heard a lot about the Vredestein Ultrac Sessanta´s performance, low noise level, tests and price (there is like $800 difference than the Dunlops). The only issue is that i´m going to be running without a spare tire and feel might be a little risky.

There is an option if I carry a air spray in case of a flat or a air compressor.

I need some help from you guys urgent

p.s. the wheels are 10" front and 11" rear wide.
