The Bridgestone Tour B XS is a tour-level urethane ball built for high swing speeds and high spin, and it’s part of the 2026 MyGolfSpy Ball Test, where it was identified as a top high-spin option for faster swingers. What Ball Lab can tell you is whether the manufacturing backs up that reputation. We measured weight, diameter, compression, roundness, and balance across 36 balls and three boxes.
Here’s what the 2026 Bridgestone Tour B XS looks like under the microscope.

Test results
The 2026 Bridgestone Tour B XS scored 84 and earned a B grade — Conditionally Recommended. The headline number reflects a profile that is strong in most categories but dragged down by compression consistency that graded at C with a spread that lands in the bottom quartile of the database.
Good Ball Rate came in at 97.2 percent. One of 36 balls was flagged as bad because it was outside the allowable compression range.
Compression symmetry averaged 1.0 points, well below the field average of 1.9 — one of the stronger results in the database and the best category on the card. Compression consistency is where the profile takes its hit, grading at C with a delta of 17.0 points and a spread running from 74.2 to 91.2. That is a wide window and means balls at opposite ends of that range will perform differently off the face.
Diameter consistency graded at A-minus and was the second-strongest category on the card alongside compression symmetry. The sample showed no consistent pole-versus-seam pattern, 32 of 36 balls fell within gauge noise. Weight consistency graded at B-plus, another solid mark.
If not for the compression consistency issues, the Tour B XS would be pushing into A territory. The rest of the profile is strong. But compression is the category that matters most for ball-to-ball performance predictability, and that is where the Tour B XS fell short.
With a score of 84, the 2026 Bridgestone Tour B XS earns a conditional recommendation. Compression consistency is the primary reason it doesn’t score higher.

Compression
Compression is a measure of how much force is required to deform a golf ball. The higher the compression value, the more force required. Consistency in that value matters because a ball that compresses differently from shot to shot produces different results from shot to shot. Ball Lab measures every ball individually and tracks the average and the spread across the sample.
The 2026 Bridgestone Tour B XS averaged 87, putting it in the firm range of our database. Compression consistency graded out at C with a delta of 17.0 points and a spread running from 74.2 to 91.2. That is well below the database average of 9.7 and is the weakest mark on the card. A spread of 17 points is wide. The softest ball in the sample and the firmest ball in the sample are measurably different products, and that variation will show up in how they perform off the face. The one bad ball is what really hurt the Tour B XS in its compression consistency.
Ball Lab also measures compression symmetry, which is distinct from the delta measurement. Where the delta tracks variation across all 36 balls, symmetry tracks how evenly compression is distributed across three points on each individual ball. The Tour B XS averaged 1.0 points of symmetry deviation, well below the field average of 1.9. It was the strongest category on the card and an elite result.
The charts below detail the compression measurements in our sample.
Weight
Weight is another metric we analyze in these Ball Lab tests. Even small differences in weight across a dozen can translate to inconsistent ball flight. Ball Lab weighs every ball to four decimal places.
The 2026 Bridgestone Tour B XS averaged 1.6054 ounces across 36 balls, on the lighter end of the database. Every ball in the sample came in under the USGA maximum of 1.6205 ounces, with a range running from 1.6025 to 1.6081 and a standard deviation of 0.0016.
Weight consistency grades out at B-plus.
The charts below detail the weight measurements in our sample.
Diameter
A ball that isn’t uniform in shape can track offline on the putting green or produce inconsistent flight patterns in the air. Ball Lab measures each ball across multiple axes to get a true picture of its shape.
The 2026 Bridgestone Tour B XS averaged 1.6824 inches, above the USGA minimum of 1.680, with a roundness deviation of just 0.0003 inches. Every ball cleared the minimum and the sample showed no consistent pole-versus-seam pattern. Thirty two of 36 balls fell within gauge noise on that measurement, meaning the shape is as uniform lot-wide as Ball Lab typically sees.
Diameter consistency graded out at A-minus. This was the second-strongest category on the card and one of the cleaner diameter profiles in the database.
The charts below detail the diameter measurements in our sample.
Ball Lab report card
Each Quality Score is a weighted average of five grades: good ball rate, compression consistency, compression symmetry, diameter consistency, weight consistency. Our scoring system punishes defective balls more severely while giving greater weight to compression metrics than to weight and diameter.
