hey guys just bought a nused 05 2500 4x4 auto and have some quick questions.

1. if i let the truck sit a couple of days. when i get in fire it up and let it idle a minute or so. when i put it in drive it really doesnt want to move. is this normal?

2. i just noticed last night while driving off throttle that my oil pressure is dropping down to between half and the quarter after half. now its always within the black marks which i assume is normal operation but its getting pretty close to the bottom side. is this normal with high ambient temps?

3. ive read around on here and have saw numerous post on tire size. people seem to be on the fence about what you can fit. as the truck sits now it has stock wheels with 33x12.50s on it. 35s would not fit with out a lift would they? i mean it looks to have plenty of room

 

That is normal, to answer questions 1 & 2, IMO.

The 35's will fit without problems.
