Wheel size

[SJenkinzz]

I have a 2004 T1950 and was wondering what the lug pattern is on the wheels. I know they are 15's. I am planning to buy new tires and thinking of upgrading to aluminum wheels. Thoughts? Opinions? They are 5 on ???
Thanks

I think its recstuff.com, they tell how to find your bolt pattern for 4,5, and 6 lug wheels. Chuck

Thanks...will measure today. Great site too...

I’m pretty sure they are 5 on 4.5”. This is how I was told to measure:
1. Hold the tape in the center of any lug.
2. Skip the next lug.
3. Hold the tape in the center of the next lug. That is the distance.

Yep, all Sunlines from about 1986-2007 had a 5 on 4.5 lug pattern, meaning 5 lugs on a 4.5" bolt circle center line. May have been earlier too, but I'm not sure what was hiding behind those hubcaps.

1986-2003 I believe had some 14x5.5 rims available with this bolt pattern, used on smaller trailers. The lug pattern is the same between them though, and they're rated for ST205/75/R14 load range C tires. Some really small trailers up through 1986 used some smaller 13" wheels, but I'm not sure of the specs on those.

1986-2003 generally 25' and larger trailers used a 15x5.5 rim, 5 on 4.5 bolt pattern, rated for a ST205/75/R15 load range C tire.

All non-slide trailers from 2003-2007, as well as Transport trailers from 2005-2007, used the 15x5.5" rim above, regardless of trailer length.

All high-profile slide trailers 1996-2007 used 15x6" rims with a 6 on 5.5 bolt pattern, rated for ST225/75/R15 load range D tires.

Any idea where i can find lug bolts for a 1983 1550, 1/2-20 threads 7/8 long threads, 20.6 mm head. 1/2-20 threads with 3/4 head does not have a large enough shoulder to seat the rim.thanks
