Quick update guys.....I've gone back to Michelin cross latitudes 235/55/17 on Devonports from the 245/65/17s bfgs and holeshots.
I have to be honest here and say the bigger all terrains looked amazing but were really effecting how the van was driving in my opinion. They just felt too big...
Firstly the van now has its spring back in its step and the autobox seems smoother and more free revving again. It also seems more confident in its gear selection where as before with the bigger tyres its did some odd things. It's also seemed to use 7th more again.
The mpg has improved massively and is getting a lot more miles per tank. This area was to be expected.
The biggest thing is the drivabilty, it just seems balanced under breaking and cornering again. Comfort levels have improved as I think the strong side walls in the bfgs could be harsh at times.
So over all I'm loving the van again, it's not quite as smart looking as the hole shots and bfgs but the lattitudes-x are a great looking tyre also. So I've found a happy medium.
Thanks for all the help guys, especially Chris over PM.
Cheers Paul. Pictures to follow soon.
