245 in front might lessen the steering response and lead to a little more tramling, but most likely splitting hairs where the PSS is concerned, although the tramling could be a concern. An interesting thing I noticed in the spec section on the various sizes of the PSS, the section width on the 275/35 is 10.9", while the 265/35 is 10.7" ..... just 2/10 of an inch .............. but the tread width on the 275/35 is 10", while the 265/35 is 10.1" ............ they basically have the same foorprint, but the 275 lists a taller sidewall. I like the benefits of a slightly higher final drive and sharper turn-in................ decisions decisions
