Sorry, think you are gonna have to explain what you already have (vehicle and tyre sizes what you plan on doing with the vehicle) and why you are going to 14's.. and mudders... IIRC 14" steel rims wont go over the brakes on a 16" sysncro.. (if it is a 16"?) overall diameter will be a lot smaller so gearing will be much lower.. smaller overall diameter means less ground clearance.. so if you need the "mud ability" 185's wouldnt be my first choice...
But.. I could be interested in the 16's..

(when i figure out just where I am going with it..

and rationalise my wheel collection..

)
I will have to update my garage with the new arrival.
Ok my van is 14" Syncro 2.1dj Panel van with Power steering. It has a camper interior and I intend on using it daily with camping trips when I'm off.
I need a tyre that is going to allow me to drive onto a muddy field, a beach, green lanes and deal with snow (on the rare occasion it comes or a holiday to eastern Europe!)
I have a set of 16" Merc wheels with 225/75/16 tyres which is an 11.04% increase in rim diameter on the original 185/85/14 set up. This causes the wheels to catch on the arches and the gearing isn't ideal. Overall, I feel it really affects the drive of the vehicle. I swapped the wheels back to original 14" size and found the drive much much better, i didn't have to work the van so hard and my mpg has jumped up to, which is a bonus.
So this has caused me to review my wheel and tyre set up. If it wasn't going to become a daily driver, it wouldn't bother me too much as it looks so much better with the 16"s on it. My standard 14" are rusty and I feel it lets the look of the van down.
So after a bit of research this morning, I have come up with a few choices. First of all, I calculated the difference in diameter for each tyre choice compared to the original 185/85/14 set up. I think I am going to stick to 16" wheels, but I need to choose my tyre carefully.
225/75/16 11.04% increase (current bfgoodrich dueller M/T)
215/65/16 2.39% increase ( My likely choice)
205/65/16 0.45% increase (no MT or AT tyre found)
195/75/16 4.33% increase
215/65/16 2.39% increase
So, now to find a good set of 205/65/16 which will be ok for day to day use but cope with the wild camping spots.
Also..... This sounds a bit daft, but does tyre size take into account the depth of the tyre tread. I.e a 205/65 road tyre is the same as a 205/65 AT tyre with tonnes of tread? If not, the difference in rim diameter could be equivalent to a different tyre size?!?!
Maybe I will post this in tyre section, just think the AT MT knowledge is likely to be found amongst the syncro folk.
