Hi Guys --
Needing new tires for our camper and wonder if ya'll can help me with a couple of questions -- confused?
The camper has two axles and a bad history of blown tires -- we have all the tires off currently and plan to replace the two oldest tires (2008) in the next day or two in prep for a trip next week.  It would be simple except there are two different tire numbers and I'm not sure which to get. 
What is the difference between st205 / 75r14 vs st205 / 75d14.  I understand one is radial, but which is the better tire for pulling a 30ft travel trailer? Two D tires with rims are cheaper than two R tires, but which is safer?
Can you mix the two types (i.e. 2 r tires and 2 d tires)?
There are two axles - does it matter where the new tires are placed (other than on the same axle)? We plan to put the new tires on the axle that always blows tires...
Thanks for your help,  shy smile

Me personally, would go with all raidials

After you get your tires and since it has a history of blowouts

You might want to look into Tyrfil

Get tires with the same load rating capacity and get trailer tires the side walls are stiffer than car tires that should solve your blow out problems.

There's a trailer shop on 17-92 a few miles south of Anthony's Pizza. They're good guys and I have bought tires for my trailers there in the past. I think they were like $75 each with new wheels and all.

But yeah, it will go down the road with mixed types. It will be a lot safer with 4 radials. Make sure they are ALWAYS inflated properly (usually around 50 PSI) and check them every time you stop for a break. You shouldn't have one that "usually blows out" under normal conditions. You might have bad bearings or even a bent axle.
