Bigger tires make fewer revs/mile which means the speedo will read slower than actual speed and odo will record fewer miles driven vs actual.
I know that but what webspoke said was is your speedo will read low by 3%. It is about 2mph at 70mph (reads 70, actually running 72) It shouldn't be 72 but 68. Like I said I like the setup but can't find wheels that look like heavy boat anchors.
I love the vision warrior wheel in this thread. Any reason this other size wouldn't work as well? I'm pretty partial to the cooper st or BF TKO. But I did like what I read about the nitto grappler and their price point is sweet.
pardon my naive-ness but my wife and i will be getting a new 12 next week and this will be my first SUV ever. just wondering what are the cons of using larger A/T tires? is there a significant impact on MPG or wear to the shocks? if there is a difference is it noticeable or drastic? thanks!
Depends what you are looking for ride wise and how you classify significant...? MPG wise you will see a drop for sure but it hasn't ever stopped me, I'd bet maybe one MPG or more depending on tire and what size. Ride quality will be affected as well. The rig will ride a little stiffer and probably have some more road noise. Your shocks shouldnt be affected. Those are the quick cons....pros they look better and perform much better off road.
IMHO the changes have never been drastic enough for me to not do it!! I will say that waaaaay back in the day my mom could always tell the difference ans *****ed about it. So who knows what your wife will think.
Has anyone tried 255/70/18 ? At 32" overall diameter but .4" more narrow than stock it seems like a winner. Doesn't even seem to be on the table as an option in all these threads though, am I missing something?
Guess I better check back in here with more info....
so I ended up buying a set of the JK Wrangler Sahara 18" stock wheels with 255/70/18 Bridgestone Dueler tires.
Tires are 32" dia. (815mm). The wheels are offset 46mm, 7.5" width instead of stock 18" WK2 at 56mm and 8" width. I'm giving up about 0.4" of tire width, but in my opinion the 32" tire size looks great on the WK2. I have no issues with clearance (have QL. checked on all settings). I don't think I'd have issues with a 275/65/18 either (don't quote me on that though....)
Have you tried the 275/65/18s yet? I have a set of these wheels and am thinking of trying the bigger tires.
Has anyone tried a 285/70-18 on Sahara 7.5x18 wheels, or any other wheel for that matter? I know the 255/70-18 will clear and these are only .5" taller and less than .5" wider but to much is still to much. What do you think?
Hello all. First post for me. Looks like a great forum.
Just picked up a 2012 Grand Cherokee Limited in BC. As I travel through mountain passes on a regular basis and need 4 wheel drive to get up my 750 meter driveway for four months of the year, I would like to get a set of winter wheels and tires to replace the stock Michelin Latitude Tour. I'm finding that aftermarket wheels are hard to come by due to the new bolt patern/size and offset. Any suggestions? Has anyone had experience with the Latitude Tour in winter condidtions? Thanks in advance.
