UH and I owning SGS-126 SN 002..... yes, normally use a 4.00 x 4.00 tire and tube....
Yes, "brake band" on tire OD may need some tweaking (due to different tire tread...).....not that a band brake worked well in the dry, forget about it on damp/wet grass....but you should be able to land slow...;-)
Trust me....BTDT.....
