Just bought an '08 Pacifica. Front tires have DOT code of 2007 so it looks like we should replace now. Problem is that I cannot find a DOT CODE on the rear tires??? I'm guessing that they are also '07's too????

Here's some info that might help to find the date code. Just a ponder if you can't find it they may be recaps on the rear?? Best of luck.

All tires by law must have a DOT serial. This includes retreads. Remember the "Full" serial that includes the date code in 3 or 4 numbers is at the end and may be on the other side of the tire.

Date code changed from 3 numbers to 4 by May 2000 as I recall so it is possible to have something like 080 on a Feb 2000 produced tire.

1991 would have only 3 numbers with the last being a 1
2001 would have 4 ending xx01 with xx being the 2digit week.

Check the other side of the tire for the DOT Code.

I wouldn't use recaps. JMHO

The letters DOT followed by the S/N are required by law. So they MUST be on other side.

Major issue with re-treads is you don't know the history of the original casings. Your size is not a high volume "standard" size used by over the highway truckers who will wear the tread off in a year or so of Intersate driving.
Back in 2012 I did a post on retreads for RV use. You might want to review the details of that post.

I think it would be false economy and you would need to do a LOT of research.

Seven years and I am replacing the fronts. Rear, I will watch and run as long as there is tread and under ten years.

We went 8+ years on our OEM Michelins (made in Spain). They were starting to show some small cracks around the lettering. Took them to Les Schwabe to have them looked at by a "professional". All he said was "yep, they're cracked".
Bought my tires from Superior tire before the FMCA got their Michelin deal going. Had to wait about a month for the two 305/70's to come in, they were only about 3 weeks old. Rears were 275/70's and were about two months old. I couldn't complain about the age at all.

You do NOT want to use recaps on an RV. The amount of damage it will inflict upon your RV when they go will make you wish you'd spent a little extra.

I just replaced all 8 of my 315/80/22.5 (Michelin XZA2) primarily due to age (they were pushing 8yrs) -- I most likely didn't need to. I know the history, I've never overloaded or ran them underinflated. Coach is always stored indoors - there was no cracking, but my wife, kids and I are embarking on a 1yr journey around the country and I just wanted the peace of mind... especially since these tires are so hard to get (they were on backorder for six months.) I them pull the best tire and I kept it as a spare in the enclosed car hauler pulled behind us. If nothing else, provides nice counterweight in the back for all of my tools in the front.

One thing to keep in mind when buying a used coach is, you don't know the history. You don't know how many curbs the previous owner has jumped, if it's been overloaded or not run at proper inflation. Assume the worst and replace at the lower end of the recommended age replacement, IMO.

The Goodyear 245 70R19.5 G159 on my 2000 GBM Class A are the original tires. The coach has lived its entire life outdoors and parked on dirt or gravel. It makes only two 120 mile roundtrips to Talladega Super Speedway each year. It's current value is less than $15k. After reading this thread from end to end it appears that my 15 year old tires have been severely abused and should be replaced before my next trip to the races. But spending $3k on a set of tires for a $12k Motorhome is a hard pill to swallow.
