Hello all,

I am considering a 07 or 08 Hemi Crew cab short box w/20's. The MDS sounds good, but looking for actual real world results. Also any opinons from owners as well please.

 

iam gettin 14 50/50 and just cruisin at 60 65 15.7 and i have a quad cab with the MDS

 

I get mid-12's in the city, mid 17's driving 65. Honestly, if gas milage is going to be an issue, don't get a big truck. Gas isn't going to get cheaper, and it might get a LOT more expensive still. Prices will stop going up when people stop buying so much, but we aren't there yet. Of course, if you NEED to get a truck, I imagine it's a buyers market right now.

 

My dads gotta 05 hemi (no mds) and it gets 14.5-15mpg...pretty light driving, 87 fuel, about 30% highway 70% town/city

 

I have an 2007 with Hemi. It is 4x2, I get 13-14 city and 18-20 highway.

 

The "20's" you want will hurt you in the mpg dept. Most report about a 1.5-2 mpg increase when switching their 20's for 17's, which is getting mentioned a lot more now that gas is about at the $4 mark.

 

2008 4x4 Quad Cab Hemi 20's under her, 15 avg in city 20+ at 60 mph to 65 on highway.

 

what? for real? I thought the shorter sidewall flex would help, not much, but still. I'd be really really surprised if it gave 1.5-2 mpg. that's freaking huge, 20% or so.

04 (No MDS) QCSB4x4hemi w/ 20"s 50/50 light foot driving with periodic 20 foot tire marks, pegged at 62-65 on the highway, 15.6 +/- .2 mpg every tank. in just highway, I'll get over 19 at 65, over 20 at 55.

 

Do a search, the 20" wheels weigh a lot more. Was a guy not a day or two ago posted that he swapped his 20's with someone for their 17's and even though they had a lot more aggressive tread, first thing he noticed was a mpg increase.
I don't know for sure if Chrysler does it, but I know F**D lists a 1 mpg difference (worse) right on the sticker with the larger wheel options.

I used to fish a lot of competitve bass tourney's before my parents got ill, I've since sold the bass boat, but remain on a couple of related forums. That's the biggie subject right now with the price of gas and these guys trailering boats all over.
It's a given that 20's handle better on pavement when towing, but they ALL are seeing better mileage when using 17" wheels. So it's become a big debate with trailer pullers now...

 

I have an 07 with oversize tires. According to the overhead computer, I am getting around 10.5 in the city and around 12.5 on the hiway. With MDS on. Not very good, but I didn't buy it for it's mpg. By the way, I use 89 octane around $4.17 here.
