I'm looking at getting all-terrain tyres for my 2019 4x4 MWB and have received conflicting advice from several tyre dealers.
Currently have the factory Contivan Contact 100s, 225/75 R16 121/120R.
Dealer 1 says the only 16" tyres available with a 121 load rating are 265/70 R16 (BFG T/A KO2) and they would fit fine. However I'd need wider rims. And it would increase diameter by 7.6% which means speedo would now read lower than I'm actually going!
Dealer 2 says I could get away with 115 load rating in a 235 width, but that 265 would protrude from the body. Otherwise nothing available in 121.
Dealer 3 says I need to stick with 121 and that nothing suitable is available.
The plate inside the front door gives max axle loads as 1860 kg (front), 2250 (rear), GVM 3550. The tyre placard gives tyre size as currently fitted i.e. 225/75 R16 121/120R
The manual has about 14 pages of tyres and tyre pressures. Based on those loads, it seems to allow for 235/65R 16C 115/113R, and some others less than 121. But it doesn't mention 245/70 R16 118R or various other sizes that look comparable. I assume from this that the manual just lists examples of tyre sizes / load ratings.
How do I know what load rating I need? What are the implications of using a lower load rating than current, say 115? Does anyone have experience using wider tyres, say 265 or thereabouts? Or any all-terrain tyres?
Can someone please help me make sense of all this?
Thanks
John
