I drive a 2011 MB E-350 Bluetec Diesel, 95,000 miles and going strong.

Because of the seven gallon Diesel Emission Fluid tank in the trunk, there is no room for a spare tire, so the car comes with Run Flat Tires. (Full disclosure, I actually like the RFT, peace of mind.)

Anyway, since the car is rear wheel drive only, I put four snow tires on it in late October, and take them off in April. I am in Connecticut.

But in 2012 when I bought the Blizzaks and wheels from Tire Rack, there were no run flat snow tires. So, I'd leave a spare summer wheel and tire in the trunk all winter just in case I got a flat, which I did once.

Anyway, after five winters it's now time to replace the Blizzaks, and I find that nobody makes 235/45R-17 Run Flat snow tires, but I can get Blizzak LM-25 or Pirelli Sottozero in 225/45R-17.

I assume that 10 mm (less than 1/3") in width will make zero difference in my life? The wheels are 7.5" wide.

Next question, the Pirellis are $175 each while the Bridgestones are $220. I've been really happy with the Blizzaks, but should I spend the extra $200 on them over the Pirellis?

So, to recap the two questions:

1. Any reason to avoid 225 tires when OEM are 235?
2. Any opinion on Pirelli at $175 vs Bridgestone at $220?

Thanks in advance

I'm a huge Pirelli fan. I have the PZero All Season Plus on my 2014 E350 sport and they have been great. I also have Pirelli Scorpion All Season Plus on my 2012 ML350 4matic. Pirelli gives great performance, grip and decent tread life.
