Predictika · Commercial truck tire orders

An AI sales agent's commercial truck tire order, checked before it goes out

An AI sales agent prepares an order for Goodyear long haul and regional truck tires, with a tire, a wheel position, a rim, a speed, an inflation pressure, an axle load, a monitoring program, an extra discount and a stated total. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the tires and returns a verdict and every reason.

Scope: Goodyear commercial truck tire orders: 29 Endurance, Fuel Max, Marathon, G316 and G622 tires in steer, drive and trailer positions, with rim, speed, spacing, pressure, load, price break, discount and fleet monitoring checks. See everything this validator covers

This validator models Goodyear commercial truck tire orders, not just the scenarios shown below.

  • Fitment — which tires the data book lists for steer, drive and trailer positions, the approved rim widths for each size, wide single tires that have no dual rating, and the minimum dual spacing for the rim.
  • Speed, pressure and load — the speed rating, the maximum inflation pressure, the pressures the load table lists, the wheel manufacturer rating, and the axle load the table allows at the chosen pressure.
  • Price, discount and monitoring — the quantity price breaks, the extra discount that needs approval or is not allowed, TPMS Plus with Fleet HQ, and the CheckPoint reader for small fleets.
  • Stated figures — the axle capacity, tire count and order total stated on the order against the figures computed from the tires, axles and price break.

Any order for these tires that touches these rules is in scope — not only the scenarios pictured here. Not covered: other Goodyear lines (mixed service, Armor Max, Kelly, Dunlop, retreads), other sizes and load ranges, and mixed sizes on one axle. Tire names, sizes, load ranges, loads, pressures, rim widths, spacing and speed ratings follow the public Goodyear engineering data book; the prices, price breaks, discount thresholds and monitoring rules are modeled, not published by Goodyear, and the prices are illustrative.

The AI sales agentBuilds the tire order from the conversation and says it is ready.

Where rules-based CPQ gets it wrong
Click to expand
    
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

    
What the validator caughtTypical rules-based CPQPredictika
Tire in the right wheel positionOnly with care
A steer-only tire, a drive tire and a trailer tire each have their own allowed positions, and all-position tires are allowed anywhere.		The tire and the position are fields of one order and are checked together on every call.
Rim, spacing and wide single tiresOnly with workarounds
The approved rim widths depend on the tire size, the dual spacing minimum shifts with the rim width, and a wide single tire has no dual rating.		Tire, rim, fitment and spacing are checked together, whatever order they were entered in.
Speed, pressure and axle loadOnly with workarounds
The speed rating, the maximum pressure, the pressures the load table lists and the load per axle depend on the tire and on single or dual fitment.		Every limit is looked up for the chosen tire and checked on every call, and each failure is reported.
Price breaks and extra discountOnly with care
The price break depends on the total tire count including spares, and the extra discount has an approval band and a hard limit.		The tire count, the price break and the discount are computed together, and the approval or block comes back with the findings.
Stated figures against computed figuresOnly with workarounds
The stated axle capacity, tire count and total depend on the tire, pressure, axles, spares, price break and discount, so any change has to be recomputed.		The stated figures are fields of the order and are compared with the computed ones on every call.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as a step is completed, so a rep often fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

  

  

    
What this validator catches: findings from its test cases

Every rule is checked on every call, in any order the choices arrive; one problem never hides another. Blocking findings stop the order; approval findings need a person to sign off; everything else is computed.

    
1The data book lists this tire in the steer section only; it is not listed for drive or trailer positions.
2The data book lists this tire in its drive section; it is not listed for steer or trailer positions.
3The data book lists this tire in its trailer section; it is not listed for steer or drive positions.
4A rim width of 900 hundredths of an inch is not on the approved rim list for this tire size.
5The duals are spaced 121 tenths of an inch apart; the minimum for this tire on this rim is 122 tenths of an inch.
6The duals are spaced 124 tenths of an inch apart; the minimum for this tire on this rim is 125 tenths of an inch.
7This is a wide single tire; the data book gives it a single load and inflation only and no dual rating.
8The operating speed of 76 mph is above the tire speed rating of 75 mph.
9The operating speed of 82 mph is above the tire speed rating of 81 mph.

13The inflation pressure of 105 psi is above the wheel manufacturer rating of 100 psi; the data book says the rim and wheel maximum must not be exceeded.
14The order does not state the wheel manufacturer rating; the data book says the rim and wheel maximum load and inflation must not be exceeded, so a person should confirm the wheels.
15The order states an axle capacity of 22,500 lbs; the data book load table gives 23,360 lbs at this pressure.
16The order states 4 tires on the axles; the axles and fitment give 8.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares an order for Goodyear long haul and regional truck tires, with a tire, a wheel position. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the tires and returns a verdict and every reason.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote 8 Goodyear Endurance RST 11R22.5 load range H tires (dual fitment) for 2 axles on the drive position. The wheel is rated to 130 psi. The rest of the request is on screen. The order states an axle capacity of 24,020 lbs, 8 tires and a total of $2,896.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with five findings, all in one answer. The data book lists this tire in its trailer section; it is not listed for steer or drive positions. A rim width of 900 hundredths of an inch is not on the approved rim list for this tire size. The operating speed of 80 mph is above the tire speed rating of 75 mph. The other two are on screen.
    6. 
      
  6. The validator returned five blocking findings in one answer. A check that reads one field at a time would pass most of this; it shows only when the choices in the order are checked against each other.
    7. 
      
  7. What this shows: for tire in the right wheel position, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the tire to Endurance LHD 11R22.5 load range G, the rim to 8.25 inch, the pressure to 105 psi, the axle load to 21,000 lbs, the stated axle capacity to 23,360 lbs and the stated total to $4,024. Four more changes are on screen.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. All five earlier findings are cleared.
    13. 
      
  13. Five problems caught in one call, fixed in one pass, and a clean $4,024 order. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
    14.
