Planti manmeri i save baim ol konstraksen kar na ol fleet menesa i no save gut long hau long makim ol standet dimensen bilong ol konstraksen kar rim taim ol i senisim o makim ol. I no olsem ol rim bilong ol pasindia kar, ol rim bilong ol konstraksen kar i bikpela moa, i gat planti kain kain spesifikasen na i gat ol kompleks paramita, na i nidim wanpela moa speselis rot bilong luksave long en. Sapos yu kliagut long sais bilong ol 'rim' tasol yu inap long makim stretpela model, na long dispela rot yu no inap long kisim 'misalignment' taim yu putim taia long en, taia i no bagarap gut, yu no inap holim gut na tu ol hevi bilong sefti.
1.Ol bikpela mak bilong ol rim bilong kar bilong wokim haus
Bikpela samting tru bilong ol rim bilong ol kar bilong wokim haus em i olsem "nominal diameter – section width/flange height", eksampel 29-13.00/2.5. Mining bilong olgeta wan wan paramita i olsem:
- 29 (nominal diameter): Nominal diamita bilong rim, ol i skelim long ins, we i makim insait diamita bilong taia we rim i wokim long fit long en;
- 13.00 (seksen wait): Wait bilong rim, ol i skelim long ins, i makim wait bilong 'load-bearing surface;
- 2.5 (flange height): Hait bilong 'flange', ol i skelim long ins, we i makim mak bilong 'rolled edge' long arere bilong 'rim'.
Ol samting we ol i save yusim long ol 'engineering vehicle rims' em: 29-inch series (eksampel. 29-13.00/2.5, 29-15.00/3.0), 25-inch series (eg. 25-11.25/2.0, 25-10.00/2.00), {{{}} inch series (eg{. 29-13.00}(eksampel)(eksampel, 4 inch, {{}}} 8.5-20, 8.8-20).
2.Tripela Ki Fiting Dimensen
Antap long ol as mak bilong longpela na bikpela bilong en, ol 'engineering steel rims' i gat tripela bikpela samting we i save makim sapos ol i ken wok gut wantaim kar:
Ol hul bilong paten/stud
PCD (Pattern/Stud Holes) i makim bikpela bilong sekol we i kamap long namel bilong ol hul bilong bolt long baksait bilong rim. Olsem, '5×114.3' i soim 5-pela hul bilong bolt wantaim namel-i go long-namel distens bilong 114.3 mm. Ol komon PCD spesifikasen bilong ol konstraksen kar i gat 5-hol, 6-hol, 8-hol na 10-hol konfiguresen, namel long ol narapela. Namba bilong ol hul na spes bilong ol hul i mas wankain stret wantaim 'wheel hub'; sapos nogat, bai i no inap long putim.
Senta Bora/Hol
Dispela i makim 'diameter' bilong 'central mounting hole' insait long 'rim'. Senta 'bore' bilong wanpela 'engineering wheel rim' i mas fit stret antap long 'axle head' bilong 'hub'; sapos 'center bore' i bikpela tumas, dispela bai mekim na 'fit' na 'wobble' i no stap gut; sapos em i liklik tumas, ol i no inap putim 'rim'. Sampela wil rim i gat wanpela 'tapered center bore' disain bilong helpim 'positioning accuracy'.
Offset (ET) Value
Dispela i makim longwe we 'mounting surface' bilong 'wheel rim' i stap longwe long 'geometric center line'. Ol wil we i gat positif ofset (positif ET veliu) bai sindaun moa insait taim ol i putim pinis, na ol wil we i gat negatif ofset (negatif ET veliu) bai sindaun moa ausait. Offset i save afektim stret 'track width' na longwe namel long ol wil rim na bodi bilong kar; em i mas makim stret bihainim ol spesifikesen bilong 'chassis' bilong kar, sapos nogat ol taia inap long 'rub' long ol 'wheel arches' o 'stability' bilong kar inap long bagarap.
3.Skelim ol Komon Enjiniaring Stiel Wil Spesifikasen
| Spesifikasen | Ol Komon Aplikesen | Ol eksampel bilong ol kar we i ken wok wantaim |
| 29-13.00/2.5 | Ol kar bilong maining i gat bikpela bodi | Tongli Heavy Industry TLD series, Taiyuan Heavy Industry TK series |
| 25-11.25/2.0 | Ol hevi-kar bilong maining | Sany SKT series, Beifang Co., Ltd. NTE series |

Ol samting yu mas tingim taim yu baim
- Bihainim gut ol tok bilong ol man i wokim: I gat ol strongpela lo bilong ol man i wokim long sais bilong ol 'enjiniaring vehicle steel rims'; ol 'dimensional parameters' i no ken senis nating. Sapos yu no givim tok orait long skruim o daunim 'rim diameter' o 'with' dispela bai senisim 'aspect ratio' bilong taia, na dispela bai bagarapim spit bilong kar, 'braking performance' na laip bilong taia;
- Sekim gut PCD na senta bore: Pastaim long baim, yu mas sekim gut 'bolt hole pitch' na senta bore dimensen bilong kar bilong pastaim o kar yu laik baim; 'offset' (ET) veliu i mas wankain stret;
- Mekim ol samting i stret wantaim ol kondisen bilong wok: Long ol hevi-kar we ol i yusim long ol maining eria, em i gutpela long makim Q355B hai-strongpela samting na ol bikpela-seksen rim; long ol jeneral enjiniaring kar, ol i ken makim Q235B materiel na standet-seksen rim;
- Ol samting yu ken mekim: Long ol samting we i no stret o ol spesel wok kondisen, plis toktok wantaim wanpela speselis kampani bilong wokim ol samting yu laikim. Anyang Anqiang Wheels Co., Ltd. i sapotim olgeta kain sais stat long 5 ins i go inap 35 ins, wantaim ol samting olsem ol samting bilong wokim, ol spesifikesen na ofset olgeta i stap bilong oda sapos yu laikim.

5.Kwikpela luksave long ol wil rim
Insait bilong ol 'engineering wheel rims' i save stap wantaim ol 'dimensional parameters', olsem: "29-13.00/2.5 - 5×114.3 - ET0" o "25-11.25/2.0 10.00/2.0". Na tu, buk bilong kar, nemplet bilong 'chassis' na saitwol bilong taia bai soim tu ol 'rim' spesifikasen we i ken wok wantaim. Taim yu makim ol rim bilong senisim, lukluk long ol spesifikasen bilong kampani i wokim pastaim long meksua olsem ol paramita i stret gut, na long dispela rot yu ken seif long draivim na ron gut long kar.
