I want wide whites but the price is just not in the budget so opting out for the narrow whites.Any one have any suggestions on what route I should take.I have all new hub caps and trim rings to fit and i know i can upgrade my rims but not sure if these will fit the newer style ones........

So we'll see how this goes... I am currently running Firestone 235 R16. They came new on the 50 3100 truck I recently purchased. I have put over a thousand miles on them without any complaints other than extra effort to steer when sitting still. In fact, this truck goes so strait down the road even at 70 MPH, I really am not looking forward to the possibility of having to replace them. Am I in danger of dying in a tragic and potentially fiery crash from tires too wide for my 4.5 inch rims?

The tires being to wide on the rims if anything might cause more wear in the center of the tires over time..... | | | | | Joined: May 2006 Posts: 8,351 'Bolter | | 'Bolter Joined: May 2006 Posts: 8,351 | Whitelightning is correct. It's not really a safety issue from the standpoint of a tire failure, but more of a vehicle handling issue. Even that can be avoided by making sure the tire pressures are correct. I don't think that the size you're running is enough to cause too much of an issue. Now if you were running 245 or wider, then it would be more of an issue, due the lack of sidewall stability.

For instance: What is the aspect ration of the 235R16 tire that was used in above posts (235/70R16 or 235/60R16 or...).
I guess I could look up stock tire diameter and do the math and figure it out myself, but just a little more information would make things so much easier. | | | | | Joined: Mar 2010 Posts: 10,290 Renaissance Man | | Renaissance Man Joined: Mar 2010 Posts: 10,290 | Sorry about that David. My feeble mind could not retain all of the numbers and letters for the length of time that it takes to walk 27 feet from where my truck is parked. Sad, I know. They are 235/70R16 (I wrote it down this time). Like I mentioned earlier, I would not have chosen these tires, but they came brand new on the truck when I bought it.

The Cooper SRM II specified diameter (on wider wheels) is about 30" (unloaded diameter?). The 6.50x16 original standard tire had about a 28" loaded diameter.
